A triboelectric nanogenerator (TENG) and an electromagnetic generator (EMG) were hybridized to harvest the human mechanical energy. By an effective conjunction of triboelectrification and electromagnetic induction, the hybridized nanogenerator with a radius of 2 cm and height of 1.2 cm could charge a 1,000 mu F capacitor to 5.09 V after 100 cycles of vibration. This mini-sized hybrid nanogenerator could then be embedded in shoes to serve as an energy cell. Typical outdoor applications-including driving with a Global Positioning System (GPS) device, charging a Li-ion battery and a cell phone-were successfully demonstrated, suggesting its potential application in smart wearable electronics and future suits of soldiers.
