An ultra-stable all-weather service piezoelectric nanogenerator (PENG) with a
wide operating temperature range (-80~80 ℃) and a wide operating relative
humidity range (0~100%) is proposed.
The PENG based on N doped 4H-SiC exhibits long-term service stability up to 50 days.
The short circuit current density of PENG based on N doped 4H-SiC is enhanced significantly.
