Brain fingerprinting is a technique developed by Lawrence Farwell that uses electroencephalography (EEG) to detect electrical brainwave responses called MERMERs that are elicited when a person recognizes familiar stimuli. It works by measuring the brain's response when a subject is exposed to words or images related to a crime. If the brainwave patterns match those that would be expected from someone familiar with the crime details, it suggests the person has knowledge of the crime. Brain fingerprinting has been used to help solve criminal cases and evaluate brain functioning, though further research with larger samples is still needed to fully validate its accuracy and capabilities.
Haptics is the science of applying touch and force feedback to human interaction with virtual environments. It allows users to feel virtual objects through haptic devices that provide tactile and force feedback. This improves realism and the sense of touch in applications like virtual reality, simulations, video games, and remote robotics. Current research focuses on advancing haptics technology to enable feeling of holograms, distant objects, and applications in fields like gaming, movies, manufacturing, and medicine.
Haptics technology uses tactile feedback to allow users to touch and feel virtual objects. It works by using haptic devices, which may provide tactile feedback through vibrations or force feedback to simulate weight and resistance. Common haptic devices include Phantom devices, which provide 3D touch feedback of virtual objects, and CyberGrasp systems, which add force feedback to each finger. Haptics have applications in video games, computers, robotics, and more. While the technology provides realistic feedback, haptic devices still have limitations like high costs, size, and limited force magnitudes. Future developments could include holographic interactions and medical applications using remote robotics.

Wireless charging is a method of charging batteries without cables or adapters by using electromagnetic fields. There are three main types of wireless charging: resonant charging, inductive charging, and radio charging. Resonant charging uses coils tuned to the same frequency to transfer power over larger distances and is used for electric cars and robots. Inductive charging creates an electromagnetic field to induce current in a receiving coil and is used for phones, MP3 players, and electric toothbrushes. Radio charging propagates radio waves to power devices like watches and hearing aids. The basic design consists of a transmitter that sends power signals, antennas to mediate between transmitter and receiver, and a receiver to rectify alternating current into direct current to charge a battery.
This document summarizes a seminar presentation on brain fingerprinting technology. Brain fingerprinting uses EEG to measure electrical brain wave responses, specifically the P300 wave, to stimuli presented on a computer in order to determine if individuals have hidden information stored in their brains. It works by presenting probes, targets, and irrelevant stimuli and analyzing the brain's differential response. There are four phases: evidence collection, brain evidence collection, computer analysis, and determining guilt or innocence. Unlike polygraph tests, it does not rely on physiological responses but on cognitive brain responses. Case studies showed it correctly identified information stored in a murder suspect's brain and its potential use in identifying trained terrorists.
The document discusses artificial eyes and how they work. It describes that artificial eyes consist of a camera, video processing unit, radio transmitter, radio receiver, and retinal implant.

It describes a transmitter that sends microwave signals along with message signals using a slotted waveguide antenna at 2.45 GHz. Mobile phones would be equipped with a rectenna and sensor to receive the microwaves and convert them to electricity to charge the phone battery. When the sensor detects an incoming call signal, it triggers the rectenna to receive power from the microwaves. This would eliminate the need for separate chargers and allow for universal wireless phone charging anywhere.
Virtual Medicine and the Role of EntrepreneursHoward Reis
This document discusses virtual medicine and opportunities for entrepreneurs. Virtual medicine, also called telemedicine, uses technology to provide clinical healthcare remotely. It is poised to grow significantly due to rising healthcare costs, more insured individuals, and reimbursement for services. While large companies have become involved, virtual medicine remains an opportunity for startups. The market need, clinical expertise, technology platforms, support systems, and current climate all contribute to chances for entrepreneurial success in areas like telemedicine platforms, telepsychology, teleradiology, and virtual healthcare providers. Wearables, big data, and machine learning also offer promising futures.

A bionic eye is an artificial device that replaces part or all of the eye's functionality. It works by stimulating the optic nerve with electrical impulses from a camera, allowing the brain to interpret images. Current models consist of a small implanted chip connected to an external camera. The Argus II system has an array of 60 electrodes on the implant that are stimulated by a processing unit to provide basic vision. While it does not fully restore sight, bionic eyes have helped many blind patients regain some ability to see and navigate independently. Researchers are working to improve the technology with higher resolution implants.
This document describes the development of an artificial vision system to cure blindness. It discusses how researchers are developing retinal implants that can process images from a camera into electrical signals that the optic nerve can interpret as vision. The system includes a miniature video camera, a processor to translate images into signals, and an infrared screen on goggles to stimulate a silicon chip implanted on the retina. This technology has potential to restore limited sight to those blinded by retinal degeneration, though it cannot currently provide high-resolution images.
This document describes the development of bionic eyes or artificial vision technology. It discusses how artificial retinas made of silicon or ceramic photocells could be implanted through microsurgery to detect light and stimulate the retina and optic nerve, restoring some vision. The artificial retina called the ASR contains over 3,500 photodiodes that convert light into electrical signals to stimulate remaining retinal cells. Surgeons implant the microchip by making small incisions in the eye and inserting the chip under the retina without external wires or batteries. This technology holds promise for restoring sight to those blinded by retinal diseases.
This document summarizes research on developing artificial vision systems to restore sight to blind individuals. It describes two main approaches: retinal implants like the artificial silicon retina that replace photoreceptors in the retina, and cortical implants that stimulate the visual cortex. The document outlines how these systems work, including capturing images with a camera and processing signals to stimulate the retina or brain. It also discusses the current limitations of artificial vision and ongoing research needed to improve image clarity and functionality for blind individuals.

The document discusses the bio electronic eye, which replaces some or all functionality of the eye using electronics. It provides a history of the development of the bionic eye, describes how the human eye works compared to the bionic version, and details the key components and working principle of the MARC retinal prosthesis system. Some advantages are that it can be implanted with minimal surgery and has low power needs, though limitations include the difficulty of repairs and high costs. The conclusion is that while full vision may not be restored, bionic eyes can help the blind see shapes and objects.
The document discusses bionic eyes and retinal implants. It begins with an introduction to bionic eyes and their potential to restore vision for the blind. It then provides details on the anatomy and function of the eye and retina. It discusses two major causes of retinal degeneration - retinitis pigmentosa and age-related macular degeneration. The document outlines the need for bionic eyes to restore lost vision. It describes the basic components and working of a bionic eye system like the Argus II, which uses a camera and transmitter to stimulate a retinal implant. The goal is to increase the resolution of implants to allow reading and facial recognition.
The Argus II is a retinal prosthesis system that provides a sense of sight to people who are blind from conditions like macular degeneration. It consists of a camera and video processing unit that captures images and converts them to electrical pulses, a transmitter that sends the pulses to an implanted retinal stimulator with electrodes, which substitutes for damaged photoreceptors. The implant stimulates the retina to allow the brain to interpret patterns of light and dark and form basic visual perceptions. Early testing shows recipients can detect shapes and motion, and the technology may eventually provide clearer vision like facial recognition.
This document summarizes research on developing artificial vision systems to restore sight for the blind. It describes two key technologies: the artificial silicon retina and artificial retina component chip. The artificial silicon retina is a microchip implanted in the eye that contains photodiodes that convert light into electrical signals to stimulate the retina. The artificial retina component chip is similar and provides a 10x10 or 250x250 pixel visual field. The document explains how these devices work and the surgical process for implantation. It also outlines an artificial vision system using a camera, signal processor and brain implants to transmit images and provide a limited form of artificial sight.
The document describes the bionic eye and how it aims to restore vision for the blind. It discusses how a bionic eye works using a camera and microchip to convert images into electrical pulses that stimulate the retina. Specific projects are mentioned, like the artificial silicon retina which is a microchip implanted in the eye containing photodiodes. The Argus II is highlighted as the first approved bionic eye system, which transmits wireless signals from eyeglass cameras to a retinal implant in order to produce spots of light that the brain interprets as vision.
This document summarizes an artificial silicon retina (ASR) seminar presentation. It describes how ASR technology works to restore vision by implanting a microchip retinal prosthesis that converts light into electrical signals. The ASR is small enough to fit in the eye and receives power from light, without needing batteries. It sends signals through the optic nerve to the brain, allowing some patients to perceive images. However, ASR technology remains highly experimental and can only provide basic vision currently. Much more research is still needed to develop it further.
The document describes the development of an "Electronic Eye" technology to help restore vision. Researchers are creating an artificial retina made of silicon microchips that can be implanted in the eye. The chips contain photodiodes that convert light into electrical signals to bypass retinal cells damaged by conditions like macular degeneration. Early results show people able to see spots of light or basic shapes. The technology relies on a small camera, processor, and implants in the visual cortex to allow some sight. This could help the millions of people worldwide suffering from blindness.
1. Scientists are developing a bionic eye called an artificial retina that could restore vision. It works by using a small implanted chip with light-sensitive cells that transmit signals to the optic nerve and brain.
2. The chip detects incoming light and transmits electrical signals to stimulate remaining retinal cells. Early versions used silicon but now scientists are testing ceramic cells that are safer for the human body.
3. The surgery to implant the chip involves making small incisions to insert the chip and use fluid to lift the retina and seal it over the chip. The goal is to replace damaged photoreceptor cells and restore basic vision.
Bionic eye is a device that can provide sight-detection of light.
Researches working for the Boston Retinal Implant Project have been developing Bionic eye implant that could restore the eye sight of people who suffer from age related blindness.
It is based on a small chip that is surgically implanted behind the retina, at the back of the eye ball.
Ultra thin wires strengthens the damaged optic nerve.
The user should wear special eye glasses battery powered camera and a transmitter.
This document discusses current research on bionic eyes and their future prospects. It begins by describing the structure and function of the human eye. It then outlines causes of blindness and eye diseases. The document introduces the concept of a bionic eye as a bioelectronic device that can replace or enhance eye functionality. It describes different regions where implants can be placed and discusses approaches like epiretinal and subretinal implantation. The rest of the document focuses on the artificial silicon retina and multiple unit artificial retina chipset system as examples of bionic eye technologies, outlining their design, advantages, and limitations. It concludes by noting the progress made in bionic devices and remaining challenges in providing power and brain interfaces.
This document discusses various techniques for studying the brain, including:
- Diffusion Spectrum Imaging (DSI) allows mapping of axonal trajectories but not individual neurons due to MRI resolution limitations.
- Two-photon microscopy can image live mouse brains up to 1mm depth. Confocal laser scanning microscopy provides high-resolution images of brain structures in vitro.
- Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) provide the highest magnifications up to 1 million times but require thin samples and only work in vitro.
Neuroprosthetics involves using brain signals acquired from neurons for various purposes like restoring movement in paralyzed patients. Nanotechnology like nano multi-electrode arrays can be used to receive and transmit brain signals more effectively by increasing electrode conduction and reducing incorrect connections with neurons. Neuroprosthetics has applications in both in vivo and in vitro contexts and can help improve functions like movement, speech, and understanding of drug effects on animal behavior and emotions.

Human visual system:
Prosthetics are artificial substitutions to the organs
of the body which are disabled. Neurons of the
human visual system exhibit electrical
properties.Cornea (dome), pupil (center of iris),
crystalline lens (inverted), vitreous retina (into
electrical pulses), optic nerves and occipital
lobe constitute basic parts of eye.
Retinal “Transducer”:
An equivalent circuit of a retina is realized
using
- A distributed MOSFET
- Three MOSFETs
- Two Photo Diodes
- Two Current Mirrors
The functions of Photoreceptors, Bipolar Cells
and Horizontal cells are implemented by this
circuit.
Neurons send and receive electro-chemical
signals to and from the brain up to

VISION FIELD OF A BLIND HUMAN:
2) BRAILLE TYPE WRITER:
• Used majorly for deaf –blind,
whose only mode of communication
remains as sense of touch.
• A miniature glass is mounted as
above.
• Using a signal processor
synchronized signals are converted to
pricking pulses, which is sensed on a
pad interfaced on the stomach or hand
of blind.
• Braille is a system of reading and
writing using raised dots in cells of six
that represents alphabets, pictures,
obstacles etc.
• Braille is written on heavy paper
using either a slate and stylus, or a
braille-writing machine (brailler)

for about 6 months to oneyear.

3) OCULAR PROSTHESIS (FALSE EYE):
Traumatic accidents and treatment of ocular and orbital cancers, blind and painful eyes, and other
diseases sometimes lead to the need for reconstruction of the orbit (eye socket). Also orbital implant
called (enucleation).
• The false eye is designed after taking moldings of the patient’s orbital tissues and
eyelids, such that, the prosthesis fits nicely and comfortably.
• The BIONIC EYE implants are of porous polyethylene, (Medpor), and of aluminum
oxide, (Bioceramic) or hydroxyapatite, kryolite glass or acrylic materials.
• After implant they allow blood vessels to grow in them.
• Usually there is a significant build-up of salt and protein deposits on the eye in one
year's time. Polishing removes these potentially irritating deposits.
• Artificial drops are added to desilt eye.
• After orbital implant, it is difficult for the casual observer to distinguish the natural
eye from the implant.
• Currently camera of 100*100 pixels has been implemented.

8. Nano Vision Chip System:
• Age related retinal diseases like macular dysfunction, retinitis
pigmentosa can be averted using nano tubes.
• Normally, when light rays or images are focused by the lens of the eye
onto the retina, light-sensitive cells called "rods" and "cones" convert the light
into electrical impulses that travel to the brain and are interpreted as images of
the world around us. "[The retina] actually does some of the image processing,
and then sends this information to the brain, and so we see.
The Nano Vision Chip System consists of
1. A low Power CMOS camera mounted on a spectacle.
2. A Image processing device
3. Transmission device
4. Signal conditioner
5. Electrode array
8
9. • CNT at Nano scale reduces background noise, magnifies signal and
provides desired redundance.
• Zinc oxide nano wires are used here to transfer the signal from the signal
conditioner to the CNT array.
• Nano batteries have long shelf life, predicted to last for 15-20 years.
The NVCS working can be studied as two parts – Intraocular and Extra ocular
Extraocular (Outside the Eye)
• The Images are received by the CMOS camera
• The microprocessor based image processor processes the images thus received.
The processing may be either digital image processing or neural based image
processing.
• The signal so obtained is PWM encoded and modulated using ASK.
5) MEMS:
(MEMS) based adaptive optics phoropter. When light enters the eye,
nearly 127 million rods and cones, which are the photoreceptors in the retina, initiate
a series of electrical signals so rapid that the images the eye receives appear to be
continuously updated in a seamless process. A breakdown in this light-conversion
process can lead to vision impairment or loss of sight. A new optical device, called the
microelectromechanical systems– (MEMS-) based adaptive optics phoropter (MAOP),
will greatly improve this process. It allows clinicians to integrate a computer-
calculated measurement of eyesight with a patient’s response to the target image.
Patients can immediately see how objects will look—and the clinician can adjust the
prescription—before they are fitted for contacts or undergo surgery. As a result,
patients will experience better vision correction outcomes, especially with custom
contact lenses or laser refractive surgery. A microelectrode array developed for a
retinal prosthesis device. The electrodes are embedded in silicone-based substrate
polydimethylsiloxane (PDMS). PDMS is a promising material for the microelectrode
array, providing flexibility, robustness, and biocompatibility for long-term
implantation.
The array will serve as the interface between an electronic imaging
system and the eye, providing electrical stimulation normally generated by the
photoreceptors that convert visual signals to electrical signals transmitted to the optic

10. nerves. The electrode array is embedded in a silicone-based substrate,
polydimethylsiloxane (PDMS).
a) A prototype of polydimethylsiloxane (PDMS) array used in testing. (b) Cross-section
of an eight-electrode PDMS device shows conductive lead and electrode metallization
contained between two layers of PDMS. Reinforcement ribs facilitate handling of the
thin PDMS device. A tack hole is used to pin the device to the retina.
The device is designed to be epiretinal; that is, it will be placed on
the surface of the retina inside the eye. The implant will overlap the center of the eye’s
visual field, which is the area affected in macular degeneration. Once implanted, a
small camera attached to eyeglasses will capture a video signal that will be processed
and transmitted inside the eye using a radio-frequency (rf) link. The rf link is
composed of an external rf coil that will either be part of the eyeglass apparatus or will
rest on the eyeball like a contact lens. Another rf coil inside the eye will pick up the
signal and transmit it to electronics that will format the signal for stimulating the
electrode array. The power for the circuitry, or microchip system, will be provided
inductively through transcutaneous coupling. That is, a coil attached to a battery on
the side of the eyeglasses will inductively generate power in a coil parallel to it under
the skin.

11. FUTURE APPLICATIONS:
1. As now, only black and white images are seen by this AVS system, research is being
carried to visualize coloured images by using optical fiber technology.
2. Research is being carried to replace the electrode implantation with ray or wave
devices
3. Reduction of electrodes to 4, by operating into optic nerve directly. It involves usage
of stimulator chip, radio antenna and signal processor.
11
12. 4. Electrical signaling, osmotic pumping, and molecular detection.
5. In the future the whole setup (excluding the camera) in NVCS can be nano
fabricated on a single chip thereby making it more feasible and sophisticated.
CONCLUSION:
• This invention is not only the fruit of one branch of science; it involves
the participation of different branches of science.
• This concludes every professional relating to a branch of science should
have a interesting view towards other branches of science also.
• “WISHING A REMARKABLE PROGRESS IN THE DEVELOPMENT OF THIS
ARTIFICIAL VISION SYSTEM, SUCH THAT EACH AND EVERY BLIND PERSON
TODAY, IS NEVER A BLIND TOMMOROW.”
• Striving to eliminate the word “BLIND” from our vocabulary.
