2. INTRODUCTION:
 Wearable biosensors are the non-obstructive devices that
overcome of the limitations of ambulatory technology.
 These can be in the form of small shirts , thin badges which
allows the continuous monitoring of BP , glucose levels and other
biometric data.
 By developing a 2 way feed back between doctors and patients ,
the wearable sensors has led to transformation of disorders.

3. DEVELOPMENTS IN
WEARABLE SENSORS:
1. Ring Sensor-
 The ring sensor is a
PULSEOXIMETRY sensor.
 Ring shaped device that
can be worn long
period.
 Helps in monitoring of
heart rate .

4. WORKING OF RING
SENSOR:
 Whenever the heart muscle contracts, then the blood
ejected from the ventricles and the transmission of
pressure pulse takes place through the circulatory
system.
 Detect the changes in the blood volume.
 This is done by photoelectric method in which the
conductors like photo resistors are mainly used.
 Light is emitted through the LED and the resistance
is observed by the total amount of light that reaches
every contraction of heart.
 voltage divider circuit is connected with the photo
resistor that produces a voltage that varies according to

5. ARCHITEC OF
SMART SHIRT:
2) Smart Shirt (Wearable Motherboard)-
Smart shirt was basically the Georgia tech wearable
motherboard (GTWM).
uses optical FIBRES TODETECT the wounds from
bullets.
It was woven into a single garment on the weaving
machine
fit 38-40” chest.

6. APPLICATIONS OF SMART SHIRTS:
 The smart shirt technology has led to
an unobstructed
 continuous monitoring for patients
 Disease management:
 High blood pressure
 Heart disease
 Diabetics
 Chronic bronchitis.

7. UPCOMING USES OF WEARABLE
SENSORS:
 3) Wearable Sensor For Preventing Road Accidents-
 Road safety is the most important issue worldwide as it
has led to the loss of precious lives.
 Wearable computers has played a major role INAVOIDING
avoiding road accidents.
 These computers also helps
in providing the information to the recovery agencies
whenever a road accident takes place.

8. Smart Clothing:
These are the shoes which allows the individual to run with a jogging
partner at distant places while remain connected to the internet.
consists of sensors and measures the impact of parts of shoe with the
ground.
Wear Cam- This is the device for effortless SISPLAY,
processing and transmission of visual imagery. The
WEARCAM is invented considering the following entities:
Cameras are attached to the body in such a way that
both the hands remain free
Ways of recording, processing and transmitting
images from the cameras
A display that has the capability of presenting the
stream of images from the camera
Internet connected shoe

9. Wearable Sensor For
Human Activity
Recognition:
In daily life, it has been a goal to understand the human
Activities.
The basic aim of human activity
recognition is to develop wearable computers having
same capabilities as human beings so that the people’s
activities can be recognized in a simple manner.
The sensing is done through low level
sensors. Then the machine learning techniques are used
to process the sensed information like noise filtering,
FEATURE extraction and classification techniques etc.

10. WRISTQUE:
 The WRISTQUE is a type of wearable computer equipped
with sensors for temperature and humidity.
 The idea is that device knows location of the user by just
connecting to base stations.
 the control system reacts to one’s preferences
without providing the explicit input.

11. Wearable Sensors To
Improve Breathing:
Breathing is a naturally occurring phenomenon.
By deep breathing in a slow and regular manner, our
heartbeat becomes smooth and regular, the blood pressure
becomes normal, which drops the stress hormones and the
muscles relaxes.
PARTS :
Wearable sensor: detects the movements of the
body due to breathing
Microcontroller: It is basically the Arduino
microcontroller which is an open source electronics
prototyping platform

12. FIBER STRETCH SENSOR:
 It is the physiological input which allows
the user to emulate the standard computer input into
non standard input.
E g. Mouse movements and key presses.

13. CONCLUSION:
 This paper is basically the comprehensive view of most
of the applications of wearable biosensors usually used
in our daily life.
 As it consists of various applications
such as ring sensor, smart shirt, health care, wound
monitoring, activity recognition, preventing road
accidents and so on.
 So, we can conclude that
from sports and fitness to clinical diagnostics, wearable
sensors have a great impact on the future care.
