Unit- 1 INTRODUCTION TO WEARABLE SYSTEMS AND SENSORS
1.3 Types of Wearable System:
1. Fitness Trackers:
A fitness tracker is typically worn around the chest, on the wrist, or ear.
They capture the number of steps you have taken and added on much more.
They also capture metrics like speed, distance, pulse, exhalation, calories
burned, and sleep.
Some fitness trackers allow you to upload data directly to your doctor.
2. Head-Mounted Displays:
Head-mounted displays are also referred to as virtual reality headsets or VR
headsets. They may be referred to as VR glasses.
It can act as a monitor or provide information that has been superimposed over
reality. This is called augmented reality (AR).
Can create a visual simulation that has built-in sensors to detect your
movements
3. Implantables
Implantables are wearable technology that contacts your body from the inside
instead of the outside.

Pacemaker and defibrillators are a type of implantable, wearable devices.
They are typically recharged wirelessly, so additional surgery is not needed.
4. Smart Clothing:
This includes a wide range of items from helmets, hats, socks, shirts, and more.
This clothing is able to monitor the physical condition of a player during training,
which can help improve performance and reduce injury.
Smart clothing is also referred to as electronic textiles or e-textiles.
One company considered putting a tracker in their clothing to determine how
often a piece of clothing was worn.
5. Smart Contact Lens:
Smart contact lenses can monitor for diseases such as cataracts, diabetes, and
glaucoma. In addition, these contact lenses have been found to help with
farsightedness or seeing up close.
There are some smart contact lenses that can operate on solar power, capture
images and videos, and are AR enabled.
They can also store these videos. Smart contact lenses fall under the category
of implantable devices.
Most smart lenses use wireless energy transfer and ultra-low-power circuits.
Some integrate tiny batteries or rely on harvesting energy from eye movements.

6. Smart Earbuds:
Earbuds have been around for quite some time and have been Bluetooth
enabled
Smart earbuds have a compass, GPS, and gyroscope built into the earbuds.
There are sensors in the earbuds that transmit information to a smartphone.
This allows the phone to know your movement and direction.
Real-Time Language Translation: Instant translation of foreign languages
(e.g., Google Pixel Buds, Timekettle).
Voice Assistant Integration: Works with Siri, Google Assistant, or Alexa for
hands-free control.
7. Smart Glasses:
They can be divided into two different groups. The first group of smart glasses
is paired with a smartphone because you need a smartphone to see images.
The other type is one that needs a wired connection to view images.
Some smart glasses are enabled by AR, giving you an immersion experience.
For example, you can read text messages and reply to them without your
hands.
8. Smart Jewellery:
This jewelry is a new way to track the health and fitness of the wearer.
One of the most well-known smart jewelry options is a smart ring.
It captures data tracking your health. This information can be reviewed at a later
time on your smartphone.
They can monitor your heart rate, sleep, and fitness and even alert you about
an incoming phone call.

9. Wearable Camera:
A wearable camera is well suited for individuals wanting to create pictures and
photos in real-time.
There are two different types of wearable cameras. The first type is a small
camera that can be worn in the ear or on helmets.
The other type is a larger version that needs an attachment to be worn.
10. Wearable Medical Devices:
Has one or more biosensors that monitor multiple types of physiological data
for the early diagnosis of diseases.
This includes activity monitors, smart clothes, and patches to help collect
relevant health data while using non-invasive device sensors.
For example, a wearable medical device can track metrics for those that suffer
from diseases related to high blood pressure or heart rate.
