Wearable electronic devices refer to textiles and clothing with integrated electronic technology or other computing devices that provide intelligent functions. These smart textiles enhance creativity, intelligence, communication skills, memory and physical senses. This definition applies not only to clothing, but also to all items that can be worn on the body. Once combined with electronic technology, such as watches, hats, shirts and glasses, they can all constitute a wide range of wearable electronic devices.

Wearable technology relies on sensors to measure how human movements provide consumers with data about themselves. With the development of sensor technology, wearable devices now have deeper measurement capabilities. Therefore, consumers have a better understanding of themselves and can change their lifestyles later.

Accelerometer

Accelerometers are sensors used in wearable devices. Their acceleration brands, such as gravity and linear, prove their sensing capabilities. At the same time, their measurement capabilities make it possible to program measurement data for different purposes. For example, a running user can access his or her maximum speed output and acceleration. In addition, the accelerometer can track sleep patterns.

Gyro

Gyroscopes are also common wearable sensors. They differ from accelerometers only in recording angular acceleration. In some embodiments, an accelerometer is used to measure rotational acceleration, and some systems want to combine the two to eliminate filtering errors. The gyroscope improves the accuracy of tracking data and provides a variety of types, including gas bearings, mechanical and optical bearings.

Magnetometer

Magnetometers can be integrated to create an inertial measurement unit (IMU) with accelerometer and gyroscope. All of these sensors can have three axes, very similar to a compass, which can improve balance. Gyroscopes and accelerometers are usually used in conjunction with them, while magnetometers match them by filtering the direction of motion.
