Abstract:

Wearable sensors have received extensive development across the world towards diverse applications in healthcare, sports monitoring, and smart home. Socks with sensing capabilities can reveal more direct sensory information on the body for longer duration in daily life. Textiles-based Triboelectric nanogenerator (T-TENG) not only could be an optimal option for scavenging low-frequency waste energy from body motions as a power source, but also can be used as self-powered sensors due to its soft, flexible, and thin characteristics. With the integration of a high-voltage diode and a mechanical switch, the T-TENG socks are able to generate a high closed-loop current which is used to harvest energy from normal walking to power a Bluetooth module for wireless sensory data transmission under Internet of Things (IoT) framework. In addition, leveraging personalized triboelectric output features, artificial intelligence (AI) based comprehensive gait analysis can tell us about the identification, health condition, and activity of the users. In general, the smart triboelectric socks offer a complete AIoT platform in the applications of foot-based energy harvesting and monitoring the diversified physiological signals for healthcare and smart homes.
