Wearable biosensors-1222865689459971-8 (1)

  1. 2. <ul><li>Need of wearable biosensors </li></ul><ul><li>Introduction </li></ul><ul><li>What is a biosensor ? </li></ul><ul><li>Properties of biosensor </li></ul><ul><li>Wearable biosensors: - </li></ul><ul><li>1. Ring sensor </li></ul><ul><li>2. Smart shirt </li></ul><ul><li>Conclusion </li></ul><ul><li>References </li></ul>
  2. 3. <ul><li>remote monitoring of patients. </li></ul><ul><li>training support for athelete. </li></ul><ul><li>monitoring of individuals who work with </li></ul><ul><li>hazardous elements. </li></ul><ul><li>tracking of professional truck driver’s vital </li></ul><ul><li>signs to alert them of fatigue. </li></ul>
  3. 4. <ul><li>Use of wearable monitoring devices allow </li></ul><ul><li>continuous monitoring of physiological signals. </li></ul><ul><li>Wearable systems are totally non-obtrusive </li></ul><ul><li>devices that allow physicians to overcome the </li></ul><ul><li>limitations of ambulatory technology. </li></ul><ul><li>detects events predictive of possible worsening of </li></ul><ul><li>the patient’s clinical situations. </li></ul>
  4. 5. A biosensor is a device for the detection of an analyte that combines a biological component with a physio-chemical detector component.
  5. 6. <ul><li>Consists of 3 parts: </li></ul><ul><li>Biological component </li></ul><ul><li>Physiochemical component. </li></ul><ul><li>Signal processor. </li></ul>
  6. 7. <ul><li>RING SENSOR. </li></ul><ul><li>SMART SHIRT. </li></ul>
  7. 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. <ul><li>works on the principle of plethysmogram and pulse </li></ul><ul><li>oximetry. </li></ul>
  8. 9. <ul><li>LED’s and Photodiodes. </li></ul><ul><li>First stage amplifier. </li></ul><ul><li>Sample and Hold circuit. </li></ul><ul><li>Signal Conditioner. </li></ul><ul><li>CPU. </li></ul><ul><li>RF Transmitter. </li></ul><ul><li>Software for the microprocessor on the ring. </li></ul><ul><li>Software for the host computer. </li></ul>LED’S and photodiodes. Micro processor(inside) Battery Transmitter
  9. 12. <ul><li>Continous monitoring. </li></ul><ul><li>Easy to use. </li></ul><ul><li>Reducing hospitalization fee. </li></ul><ul><li>Initial cost is high. </li></ul><ul><li>Limited number of physiological parameters can </li></ul><ul><li>be monitored. </li></ul>
  10. 13. Fig. Smart Shirt System.
  11. 16. <ul><li>Easy to wear and take off. </li></ul><ul><li>Continous monitoring. </li></ul><ul><li>Initial cost is high. </li></ul><ul><li>Battery life is less. </li></ul>
  12. 17. <ul><li>Smart shirt technology opens up existing opportunities to </li></ul><ul><li>develop adaptive & responsive systems that can think & </li></ul><ul><li>act based on the user conditions stimuli & environment. </li></ul><ul><li>Certain individuals are susceptible to anaphylaxis reaction </li></ul><ul><li>(an allergic reaction) when stung by a bee or spider and need </li></ul><ul><li>a shot of adrenaline immediately to prevent further fatalities. </li></ul><ul><li>by applying advancements in MEMS(Micro-Electrochemical </li></ul><ul><li>systems) technology we can achieve that. </li></ul><ul><li>The Smarts shirt’s delta acquisition capabilities can be used to </li></ul><ul><li>detect the condition when an individual is lapsing into a diabetic </li></ul><ul><li>shock and this integrated feedback mechanism can provide the </li></ul><ul><li>appropriate response to prevent a fatality. </li></ul>
  13. 18. <ul><li>Just as special-purpose chips and processors can be </li></ul><ul><li>plugged into a computer motherboard to obtain the </li></ul><ul><li>the required information processing capability, the smart </li></ul><ul><li>shirt is an information infrastructure in which the wearer </li></ul><ul><li>can “plug in” the desired sensors and devices, thereby </li></ul><ul><li>creating a system for monitoring vital signs in an efficient </li></ul><ul><li>and cost effective manner with a “universal” interface of </li></ul><ul><li>clothing. </li></ul><ul><li>Just as the spreadsheet pioneered the field of information </li></ul><ul><li>processing that brought “computing to the masses”.It is </li></ul><ul><li>anticipated that the smart shirt will bring personalized & </li></ul><ul><li>affordable healthcare monitoring to the population at </li></ul><ul><li>large. </li></ul>
