Energy harvesting by chandan kumar
In modern days, the use of energy consumption increasing very rapidly. Fossil fuels are finite and environmentally costly. Sustainable, environmentally benign energy can be derived from nuclear fission or captured from ambient sources. Large-scale ambient energy (eg. solar, wind and tide), is widely available and large-scale technologies are being developed to efficiently capture it. At the other end of the scale, there are small amounts of ‘wasted’ energy that could be useful if captured. Recovering even a fraction of this energy would have a significant economic and environmental impact. This is where energy harvesting (EH) comes in.

Footstep power generation system
This document is a thesis submitted by Adarsha Pattnayak for the partial fulfillment of a diploma in electrical engineering. It proposes a footstep power generation system that uses piezoelectric sensors to convert the mechanical energy from footsteps into electrical energy.

Photovoltaic panels that conform to curved or irregular surfaces offer advantages over traditional rigid solar panels. Building-integrated photovoltaics can be directly applied to building surfaces or incorporated into building materials like shingles. Flexible solar panels could be purchased at home improvement stores and easily installed on homes or vehicles without heavy equipment. Organic photovoltaics have reached efficiencies of around 10% but further development is needed to improve efficiency and lifetime. Flexible electronics have potential applications in wearable devices, medical implants, smart textiles, and printed electronics for military uses.

FOOT STEP POWER GENERATION IS MODERN METHOD OF GENERATE ELECTRICITY WITHOUT WASTING ANY FUEL SOURCE.
FOOTSTEP%20POWER%20GENERATION.pptx
This document describes a project to generate electricity from footstep force using piezoelectric sensors. The system is intended to harness wasted human locomotion energy and convert it to usable electricity. It works by using piezoelectric crystals that generate a voltage when pressure is applied from stepping on them. This voltage can then be stored in a lead acid battery and used to power small electronic devices. The document outlines the components, working principle, advantages and potential applications of using this footstep power generation system in places with high foot traffic like train stations or malls.

Digitalimageprocessing
This document discusses digital image processing in medical applications. It begins by introducing medical imaging and how it is used to identify diseases by producing images of internal body structures. It then describes different types of medical images like binary, grayscale, and color images. Specific medical imaging technologies are explained like X-ray imaging and computed tomography (CT). The document also covers digital image processing techniques including histogram processing, image enhancement, and image segmentation. It concludes by discussing advantages and disadvantages of digital images as well as applications of digital image processing in medicine.
Neurallink
The document discusses brain-computer interfaces (BCI), including a brief history starting with Hans Berger's discovery of EEG in 1924. It describes invasive, semi-invasive, and non-invasive BCI types, with invasive having higher accuracy but risks from surgery, and non-invasive using EEG, MRI, or other external measures. Potential applications include assisting paralyzed patients, memory functions, and direct brain-to-brain communication. BCI is presented as an advancing technology with applications in machine control, human enhancement, and more.
CHARGE COUPLED DEVICES
This document summarizes charge coupled devices (CCDs). CCDs are light-sensitive integrated circuits that convert light into electrical charge. They are used in digital cameras, video cameras, and astrophotography to capture light and convert it to digital data. The document describes the different types of CCDs and explains their working principle. It details the three phases of image capture - clearing, exposure, and readout. Applications and advantages of CCDs are also discussed.

touch screen
Touch screen technology allows users to directly interact with digital displays through touch. It originated in 1948 with an electronic musical instrument and has since been used in a variety of applications like kiosks, industrial controls, smartphones, and ATMs. There are different types of touch screen technologies including resistive, capacitive, and surface acoustic wave. Surface acoustic wave uses sound waves generated on the screen from a touch. While touch screens offer advantages in usability and design flexibility, they can also be difficult to operate for some users and prone to dirt and scratches on the display surface. Overall, touch screen technology provides an intuitive user-friendly interface that has become widely adopted.
Crystal tester
This document describes a simple circuit that can be used to test crystals before using them in other circuits. The circuit uses two BC547 transistors, resistors, capacitors, diodes, and the crystal under test. If the crystal is good, it will cause the oscillator formed by the first transistor, resistors and capacitors to oscillate. This oscillation is rectified and used to power a second transistor and LED, indicating whether the crystal is good or faulty.

Piezo electric100 ppt
- 2. ABSTRACT Energy harvesting becomes more and more important in our life. Energy is harvested from ambient environment such as mechanical, thermal, light, electromagnetic, human body, and etc to replace traditional sources. Mechanical energy harvesting is the most promising of several energy harvesting techniques: it uses piezoelectric (PE) components that transfers the vibration energy to the electrical energy. This electrical energy can be regulated and stored before using by the electronic devices where the replacement of the batteries is impractical, such as the wireless micro sensor networks, implementable medical electronic, and tire pressure sensor system.
- 3. INTRODUCTION Piezo electric effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress Piezo electricity is derived from greek word “piezo” or “piezein”. Which means to squeeze or press Piezo electric effect is formed in crystal having no centre of symmetry Piezo electricity was first proved by french physicist btothers pierre and jacques curie
- 4. MATERIALS EXHIBIT PIEZO ELECTRIC EFFECT •Quartz •Ammonium dihydrogen phosphate (ADP) •Lithium sulfate •Rochelle salt. •Antimony sulfoiodide •Piezoelectric ceramics Barium titanate (TB-1) •Calcium barium titanate (TBK-3). .Dry bone
- 5. WORKING Crystals which acquire a charge when compressed, twisted or distorted and vice versa are said to be piezoelectric materials When piezo electric materials are subjected to stress charges are distibuted and create potential difference
- 6. APPLICATIONS 1.Sensing instrument(eg.pressure detection) 2.Ultra sonic sensors 3.Electric ciggar lighter 4.Mobile phones and kreypads 5.Series of crystalls used to blow lights 6.Gyms and working places 7.Piezo electric motars
- 7. ADVANTAGES It is a green energy pollution free Maintanence cost is low Easy replacement of equipment
- 8. DISADVANTAGES Crystals is break due to high stress Power out put is too low May effect due to temperature Low energy density
- 9. Conclusion The goal of the project is to determine if it is possible to change a personal electronic device using wasted energy harvested from walking or jogging. I used a piezoelectric strip that generated energy when bent. The output of the piezoelectric plate was connected to an energy harvesting device and whose output was connected to either a battery or super capacitor. Once this device was charged, it was connected to an electronic device, such as an iPod, for final charging.
