Transcript

  • 1. WEARABLE BIOSENSORS H.S.RAJU
  • 2. INTRODUCTION
    • WEARABLES
      • Objects that can be worn on body
      • Ex: wrist watches, rings, clothes, spectacles, etc,.
    • BIOSENSORS
      • Detects analyte
        • Biological component
        • Physiochemical component
    WEARABLE BIOSENSORS = WEARABLES + BIOSENSORS
  • 3. WEARABLE BIOSENSORS Fig 1: Photograph of ring sensor, size of the top board is 0.8 x 0.8 inch.
  • 4. COMPONENTS
    • Sensitive Biological Element
    • Transducer
    • Associated Electronics
    Fig2: Schematic diagram showing main components of a biosensor.
  • 5. WORKING Fig 3: Working of Biosensor a – analyte b – Interferent c – immobilized biological molecule d – Biospecific immobilization surface e – chemical signal f - transducer g – amplification and control unit h – output of measured analyte
  • 6. OPERATION
    • WITHOUT BIOSENSORS
  • 7. OPERATION
    • WITH BIOSENSORS
  • 8. TYPES OF BIOSENSORS
    • Calorimetric biosensors
    • Potentiometric biosensors
    • Amperometric biosensors
    • Optical biosensors
    • Piezo-electric biosensors
    • Immunosensors
  • 9. MANUFACTURING OF BIOSENSORS
    • Making of Base Electrode
    • Developing the Transducer for the reaction
    • Producing Individual Biosensors
  • 10. DEVELOPMENTS
    • Ring Sensor
    • Smart Shirt
  • 11. RING SENSOR
    • Monitors heart rate and oxygen saturation
    • It is a pulse oximetry sensor.
    • Is mainly based on
    • optical biosensors.
    • CR2032 Battery
    • ATmel ATmega 128L
    • processor
    LED’S and photodiodes. Microprocessor (inside) Battery Transmitter
  • 12.
    • Continuous monitoring.
    • Easy to use.
    • Reducing hospitalization fee.
    • Initial cost is high.
    • Limited number of physiological parameters can be monitored
    Advantages Disadvantages
  • 13. SMART SHIRT
  • 14.
    • Easy to wear and take off.
    • Continuous monitoring.
    • Initial cost is high.
    • Battery life is less.
    Advantages Disadvantages
  • 15. APPLICATIONS
    • Health Care
    • Industrial Process Control
      • Online control.
      • Offline control (Distant and Local).
    • Military Applications
      • Continuous
    • Environmental Monitoring
  • 16. ADVANTAGES of WEARABLE BIOSENSORS
    • Rapid continuous control
    • Facilitates continuous monitoring
    • Detection of transient phenomena
    • Easy to use
    • Reducing hospitalization fee
    • Accurate
  • 17.
    • Heat sterilization is not possible
    • Membrane may be fouled by deposits
    • Intoxication of cells present in biosensor
    • Changes can put mechanical and chemical stress on the biosensor
    • Initial cost is high
    • Battery life is less
    DISADVANTAGES of WEARABLE BIOSENSORS
  • 18. FUTURE TRENDS
    • Magneto biosensors
    • Flame retardants
    • Personal care products
    • Greater use of home-based monitoring and treatment
    • Intelligent control of medication delivery (e.g. insulin delivery based directly on blood glucose levels)
    • Greater use of nanotechnology and micro fluidics (“lab on a chip”)
    • Implementation using biochemistry, chemistry, thin-film physics, and electronics
  • 19. CONCLUSION
    • Applied to a restricted area of the potential market
    • Limitations: sensitivity, response time, and lifetime
    • Immobilization techniques nanotechnology, miniaturization, and multisensor
    • Improvement in the affinity, specificity, and mass production of the molecular recognition components
    • Development of advanced receptors and molecular recognition elements
