3. INTRODUCTION
 WEARABLE BIOSENSORS = WEARABLE + BIOSENSOR
 WEARABLES :- BIOSENSORS :-
 Objects that can be worn - Detect analyte
on body -Biological
component
Ex: wrist watch, rings, -Physiochemical
component
clothes, spectacles, etc…

4. COMPONENTS OF A BIOSENSOR
 Sensitive Biological Element
 Transducer
 Associated Electronics

5. How does a biosensor works?
 Use of wearable monitoring devices allows
continuous monitoring of physiological signal
 Wearable systems are totally non-obstructive
devices that allow physicians to overcome the
limitation of ambulatory technology
 Detect event predictive of possible worsening of
the patient’s clinical situations

6. Need for a wearable biosensor
 Remote monitoring of patients
 Training support for athletes
 Monitoring of individuals who work with
hazardous elements
 Tracking of professional truck driver’s vital
signs to alert then of fatique

7. What is a Wearable Biosensor?
 Wearable monitoring device that allows continuous
monitoring of physiological signals.
 They rely on wireless sensors enclosed in items that can
be worn, such as ring or shirt.
 The data sets recorded using these systems are then
processed to detect patient’s clinical situations.
 Biosensor is an analytical device, which convert a
biological response into electrical signal.

8. OPERATION
WITH BIOSENSOR :-
 WITHOUT BIOSENSORS :-

9. OPERATION
WITHOUT BIOSENSOR :-

10. TYPES OF BIOSENSORS
 Calorimetric biosensor
 Potentiometric biosensors
 Amperometric biosensors
 Optical biosensors
 Piezo-electric biosensors
 Immunosensors

11. MANUFACTURING OF BIOSENSORS
 Making of Base Electrode
 Developing the Transducer for the reaction
 Producing Individual Biosensors

12. DEVELOPMENTS
 Ring Sensor
 Smart Shirt

13. RING SENSOR
 Monitors heart rate and oxygen saturation
 It is a pulse oximetry sensor.
 It mainly based on optical biosensors.
 CR2032 Battery
 Atmel AT mega 128L processor

14. SMART SHIRT

15. Advantages
 Continuous monitoring.
 Easy to use.
 Reducing hospitalization fee
DISADVANTAGES
 Initial cost is high
 Limited number of physiological parameters can be
monitored

16. APPLICATIONS
 Health Care
 Industrial process Control
 - Online control
 - Offline control
 Mititary Applications
 - Continuous
 Environmental Monitoring

17. ADVANTAGES of WEARABLE BIOSENSORS
 Rapid continuous control
 Facilitates continuous monitoring
 Detection of transient phenomena
 Easy to use
 Reducing hospitalization fee
 Accurate

18. DISADVANTAGE of WEARABLE
BIOSENSORS
 Heat sterilization is not possible
 Intoxication of cell present in biosensor
 Changes can put mechanical and chemical stress on the
biosensor
 Initial cost is high
 Battery life is less

19. 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 chio”0
 Implementation using Biochemistry, Chemistry, thin-film
physics, and electronics.
