We demonstrate a stretchable hybridized
nanogenerator based on
a highly conductive fabric of glass fibers/silver nanowires/polydimethylsiloxane.
Including a triboelectric nanogenerator and an electromagnetic generator,
the hybridized nanogenerator can deliver output voltage/current signals
from stretchable movements by both triboelectrification and electromagnetic
induction, maximizing the efficiency of energy scavenging from one
motion. Compared to the individual energy-harvesting units, the hybridized
nanogenerator has a better charging performance, where a 47 μF
capacitor can be charged to 2.8 V in only 16 s. The hybridized nanogenerator
can be integrated with a bus grip for scavenging wasted biomechanical
energy from human body movements to solve the power source issue of
some electric devices in the pure electric bus
