Sensors detect and respond to physical inputs like light, heat, and motion. Wearable devices often include sensors and can monitor health and fitness by tracking vital signs, location, and other data. There is a need for wearable systems as they can diagnose, monitor, and prevent illnesses by collecting physiological data and encouraging behavior changes through increased self-awareness. Examples of wearable devices include smartwatches, fitness trackers, and smart clothing that can monitor biometrics.

3. What is
Sensor
?
A sensor is a device that
detects and responds to
some type of input from the
physical environment. The
specific input could be light,
heat, motion, moisture,
pressure, or any one of a
great number of other
environmental phenomena.

4. Every sensor has different principle of operation, based on
the type of physical quantity it is measuring. The idea is to
create a change in the property/properties
of sensor (such as resistance, density, shape, temperature
etc) as a function of the physical quantity under
measurement.

1. Temperature Sensor
2. Proximity Sensor
3. Accelerometer
4. IR Sensor (Infrared Sensor)Pressure Sensor
5. Light Sensor
6. Ultrasonic Sensor
7. Smoke, Gas and Alcohol Sensor etc......

6. Wearable technology (also
called wearable gadgets) is a category of
technology devices that can be worn by a
consumer and often include tracking
information related to health and fitness.

7. How this wearable
device works?
Sensors can also be attached around a wearable
device to allow them to monitor various activity in the
area. Most sensors can track motion, brain activity,
heart activity, and muscle activity.
Miniature computers are also inside some wearable
devices, similar to how smartphones have miniature
processors inside of them.

9. Need for Werable
systems
A wearable device is often
used for tracking a
wearer's vital signs or
health and fitness related
data, location, etc.
Medical wearables with
artificial intelligence and
big data are providing an
added value to healthcare
with a focus on diagnosis,
treatment, patient
monitoring and prevention.

10. Need for Wearable
systems To diagnose, monitor and
prevent future illnesses,
healthcare professionals now
routinely use wearable
devices such as fitness trackers
or phones. By monitoring
physiological data and behavior,
these devices boost self-
awareness and encourage
behavior change.

11. SMART
CLOTHING
Clothing that monitors the
wearer's physical
condition. Smart shirts and
body suits provide biometric
data, such as pulse rate,
temperature, muscle stretch,
heart rhythm and physical
movement, and the data are
transmitted via Bluetooth to
an app in real time.
