Development of a Smart Wearable Device for Human Activity and Biometric Data Measurement

This paper presents a smart wearable device cooperating with smartphones to measure and utilize human activity and biometric data such as motion tracking, photoplethysmography (PPG), skin temperature (SKT), and galvanic skin response (GSR). It is comfortably designed and implemented as a wristband-type device and provides wireless Bluetooth Low Energy (BLE) connection to smartphones based on the Android operating system. According to the predefined packet format and control commands, the proposed smart wearable device can transmit measured sensing data and update its firmware. Implemention results verify the feasibility and usability of the proposed smart wearable device. It can be applied to various healthcare and wellness services or even emotional game applications.
