Power-generating footwear based on a triboelectric-electromagnetic-piezoelectric hybrid nanogenerator

Triboelectric nanogenerators (TENGs) are the most viable solution to harvest energy from low-frequency mechanical motions. Here, a triboelectric nanogenerator, an electromagnetic generator (EMG) and a piezoelectric nanogenerator (PENG) were hybridized and implemented inside a shoe sole to harvest energy from human walking. To optimize the TENG, we developed and studied three different structures (parallel, arcked and zigzag triboelectric plates)...
