The honeycomb-shaped triboelectric nanogenerator (H-TENG) proposed in this study is designed with high spatial density and extendibility for effective human kinetic energy harvesting. The H-TENG demonstrates excellent electricity generation performance in output experiments and can power various electronic devices as well as serve as a biomechanical sensor.
Triboelectric nanogenerator (TENG) is an attractive approach to power wearable electronic devices by harvesting energy from the environment. To further improve the electricity generation efficiency, a honeycomb-shaped triboelectric nanogenerator (H-TENG) with high spatial density and extendibility for human kinetic energy harvesting and motion monitoring is proposed. The honeycomb structure enables the H-TENG to extend and stack along the required direction when in restricted space, which consequently achieves enhancive space utilization and power density promotion. 3D-printed thermoplastic polyurethane as the elastic shell endows the H-TENG with robust mechanical flexibility, high deformation, and advantageous fatigue resistance. In the output experiment, H-TENG exhibits excellent electricity generation performance, that the maximum open-circuit voltage and power density can reach 1500 V and 10.79 W m(-2). In addition, the H-TENG can not only light 252 white light-emitting diodes with tapping, power the electronic watch and pedometer with walking, but also can maintain the sustainable running of the electronic thermometer. Moreover, H-TENG manifests an extraordinary sensible response to the elbow bending of different angles and can estimate the walking speed from the frequency, demonstrating the potential of H-TENG both as the biomechanical sensor and energy harvester of human movement.
