Researchers at Dongguk University in South Korea have developed a flexible, battery-free electronic device that can harvest energy from human movement and use it to power neuromorphic sensing and learning functions.
The technology could eventually be used in wearable health-monitoring systems, electronic skin, smart prosthetics, human-machine interfaces and intelligent motion-monitoring devices without requiring conventional batteries or an external power supply.
The system reminds us of the Seiko Kinetic watch (main image), first released in 1988, which also harvested energy from the movement of the wearer.
Led by Professor Sejoon Lee of Dongguk University’s Department of System Semiconductor, the research team combined a triboelectric nanogenerator, or TENG, with a flexible graphene-channel ion-gel-gated transistor.
