A hybridized self-powered textile for simultaneously collecting solar energy and random body motion was demonstrated.
Electromagnetic generators (EMGs) and triboelectric nanogenerators (TENGs) are the two most powerful approaches for harvesting ambient mechanical energy, but effectiveness of each depends on triggering frequency. Here, after systematically comparing performances EMGs TENGs under low-frequency motion (<5 Hz), we demonstrated that output performance is proportional to square frequency, while approximately in proportion Therefore, TENG has a much better than EMG at low frequency (typically...
