Three-dimensional ultraflexible triboelectric nanogenerator made by 3D printing

A practical, ultraflexible and three-dimensional triboelectric nanogenerator (3D-TENG) is fabricated by hybrid 3D printing. The ultraflexible 3D-TENG can be easily applied for biomechanical energy harvesting under low frequency human motions. The self-powered wearable devices such as LEDs flickering and buzzing SOS distress systems, and smart LEDs lighting shoes are successfully demonstrated. Especially, an ultraflexible self-powered source which provides enough power for driving and charging common electronics, is also successfully developed (such as, a temperature sensor and a smart watch).243
