An air-cushion triboelectric nanogenerator integrated with stretchable electrode for human-motion energy harvesting and monitoring

An air-cushion triboelectric nanogenerator is developed to harvest human-motion energy and monitor three movements-normal walking, running and jumping. Upon using fully sealed structure and stretchable electrode, an optimal power density of 44.6 mW m-2 is achieved to power electronics. A force detecting sensitivity of 33.8 μA Mpa-1 applies to motion recognition.445
