Wearable biosensors-1222865689459971-8 (1) Presentation Transcript

  • 1.  
  • 2.
    • Need of wearable biosensors
    • Introduction
    • What is a biosensor ?
    • Properties of biosensor
    • Wearable biosensors: -
    • 1. Ring sensor
    • 2. Smart shirt
    • Conclusion
    • References
  • 3.
    • remote monitoring of patients.
    • training support for athelete.
    • monitoring of individuals who work with
    • hazardous elements.
    • tracking of professional truck driver’s vital
    • signs to alert them of fatigue.
  • 4.
    • Use of wearable monitoring devices allow
    • continuous monitoring of physiological signals.
    • Wearable systems are totally non-obtrusive
    • devices that allow physicians to overcome the
    • limitations of ambulatory technology.
    • detects events predictive of possible worsening of
    • the patient’s clinical situations.
  • 5. A biosensor is a device for the detection of an analyte that combines a biological component with a physio-chemical detector component.
  • 6.
    • Consists of 3 parts:
    • Biological component
    • Physiochemical component.
    • Signal processor.
  • 7.
    • RING SENSOR.
    • SMART SHIRT.
  • 8. Fig 1. photograph of ring sensor,size of the top board is 0.8 x 0.8 inch. Fig 2. ring sensor weared on a finger.
    • works on the principle of plethysmogram and pulse
    • oximetry.
  • 9.
    • LED’s and Photodiodes.
    • First stage amplifier.
    • Sample and Hold circuit.
    • Signal Conditioner.
    • CPU.
    • RF Transmitter.
    • Software for the microprocessor on the ring.
    • Software for the host computer.
    LED’S and photodiodes. Micro processor(inside) Battery Transmitter

  • 12.
    • Continous monitoring.
    • Easy to use.
    • Reducing hospitalization fee.
    • Initial cost is high.
    • Limited number of physiological parameters can
    • be monitored.
  • 13. Fig. Smart Shirt System.
  • 14.  
  • 15.  
  • 16.
    • Easy to wear and take off.
    • Continous monitoring.
    • Initial cost is high.
    • Battery life is less.
  • 17.
    • Smart shirt technology opens up existing opportunities to
    • develop adaptive & responsive systems that can think &
    • act based on the user conditions stimuli & environment.
    • Certain individuals are susceptible to anaphylaxis reaction
    • (an allergic reaction) when stung by a bee or spider and need
    • a shot of adrenaline immediately to prevent further fatalities.
    • by applying advancements in MEMS(Micro-Electrochemical
    • systems) technology we can achieve that.
    • The Smarts shirt’s delta acquisition capabilities can be used to
    • detect the condition when an individual is lapsing into a diabetic
    • shock and this integrated feedback mechanism can provide the
    • appropriate response to prevent a fatality.
  • 18.
    • Just as special-purpose chips and processors can be
    • plugged into a computer motherboard to obtain the
    • the required information processing capability, the smart
    • shirt is an information infrastructure in which the wearer
    • can “plug in” the desired sensors and devices, thereby
    • creating a system for monitoring vital signs in an efficient
    • and cost effective manner with a “universal” interface of
    • clothing.
    • Just as the spreadsheet pioneered the field of information
    • processing that brought “computing to the masses”.It is
    • anticipated that the smart shirt will bring personalized &
    • affordable healthcare monitoring to the population at
    • large.
