BIO SENSORS BY DHAVAL MAJITHIA AND GROUP

  1. 1. BIO SENSORS GUIDED BY PROF. SANDEEP PARIYANI DEPARTMENT OF E&C, MEFGI-RAJKOT. PREPARED BY DHAVAL B. MAJITHIA PARTH M. JAKHRIYA SAGAR V. TAMALIYA
  2. 2. SENSOR A sensor that integrates a biological element with a physiochemical transducer to produce an electronic signal proportional to a single analytic which is then conveyed to a detector
  3. 3. BIO SENSOR A Biosensor is a self-contained Integrated Device that is capable of providing specific quantitative or semi- quantitative analytical information using a bio logical element which is contact with a transduction element. This is a device that uses specific biochemical reaction to detect chemical compound in biological compound.
  4. 4. FATHER OF BIO SENSOR Leland C. Clark Jr. (1918–2005) was an American biochemist born in Rochester. He is most well known as the inventor of the Clark Electrode, a device used for measuring oxygen in blood, water and other liquids. Professor Leland C Clark Jnr
  5. 5. BASIC CHARACTERISTICS  LINEARITY: Linearity of the sensor should be high for the detection of high substrate concentration.  SENSITIVITY: The Value of the electrode response per substrate concentration.  SELECTIVITY: Chemicals Interference must be minimized for obtaining the correct result.  RESPONSE TIME: Time necessary for having 95% of the response.
  6. 6. SENSING TECHNIQUES Fluorescence DNA Microarray SPR Surface plasmon resonance Impedance spectroscopy SPM (Scanning probe microscopy, AFM,STM) QCM (Quartz crystal microbalance) SERS (Surface Enhanced Raman Spectroscopy) Electrochemical
  7. 7. COMPONENTS OF BIOSENSOR The Three main components of biosensors are: •Biological element: For sensing the presence and concentration of a substance. •Transducer: The product of interaction of biological component and sample may be a suitable chemical, charge etc., which can be converted by transducer into an electrical signal. •Associated Electronic Devices: The electrical signal may be further amplified and can be read on digital panels
  8. 8. BIO SENSORS Glucose Monitoring Device Glucose Monitoring Device is used to monitors the glucose level in the blood. It is mostly useful for diabetes patient to know his/her diabetes level so the doctor treat them well as soon as possible.
  9. 9. RING SENSOR It is a pulse proximetry, i.e. it monitors the oxygen saturation. It is based on the concept of photoconductor. Principles :- Blood pressure pulse causes vessel wall displacement. Detection pulsatile blood volume changes by photoelectric method by photo resistor Connected as a part of voltage divider circuit and produces a voltage that varies with the amount of blood in the finger.
  10. 10. WORKING OF RING SENSOR In order to detect blood volume changes due to heart contraction and expansion by photoelectric method, normally photo resistors are used. Light is emitted by LED and transmitted through the artery and the resistance of photo resistor is determined by the amount of light reaching it. Oxygenated blood absorb more light than deoxygenated blood A noise cancellation filter is used to cancel the noise due to motion of the finger.
  11. 11. ADVANTAGES  Continuous monitoring.  Easy to use.  Reducing hospitalization fee DISADVANTAGES  Initial cost is high.  Limited number of physiological parameters can be monitored.
  12. 12. SMART SHIRTS It is also known as GTWM i.e. Georgia Tech Wearable Motherboard. This GTWM (smart shirt) provides an extremely versatile framework for the incorporation of sensing, monitoring and information processing devices. .It is used to integrate sensors for monitoring the vital signs like temperature, heart rate and respiration rate. It uses optical fibers to detect bullet wounds and special sensors and interconnects to monitor the body vital signs during combat conditions
  13. 13. WORKING OF SMART SHIRT A combat soldier sensor to his body, pulls the smart shirt on, and attaches the sensors to the smart shirt. A “signal” is sent from one end of the plastic optical fiber to a receiver at the other end. The emitter and the receiver are connected to a Personal Status Monitor (psm) worn at the hip level by the soldier. If the light from the emitter does not reach the receiver inside the PSM, it signifies that the smart shirt has been penetrated (i.e.; the soldier has been shot). The signal bounces back to the PSM forum the point of penetration, helping the medical personnel pinpoint the exact location the solider wounds.
  14. 14. ADVANTAGES  Continuous monitoring.  Right Treatment at the right time  Easy to wear and takeoff. DISADVANTAGES  Initial cost is high  Battery life is less
  15. 15. APPLICATIONS  Food Analysis  Study of biomolecules and their interaction  Drug Development  Crime detection  Medical diagnosis  Environmental field monitoring  Quality control  Industrial Process Control  Detection systems for biological warfare agents  Manufacturing of pharmaceuticals and replacement organs Detection of toxic metabolites such as fungi Remote sensing of airborne bacteria e.g. in counter-bioterrorist activities
  16. 16. CONCLUSION It is applied to restricted area of potential market. The limitations is Sensitivity And battery life. This is advanced technologies such as the smart shirt have at partial to dramatically alter its landscape of healthcare delivery and at practice of medicine as we know them today. It is leading to the realization of “Affordable Healthcare, Any place, Anytime, Anyone”.
