A Faraday Cage‐Inspired Triboelectric Nanogenerator Enabled by Alloy Powder Architecture for Self‐Powered Ocean Sensing

Self‐powered sensing technologies are increasingly sought for intelligent and autonomous marine environmental monitoring. A Faraday cage‐enabled triboelectric nanogenerator (FC‐TENG) is developed by incorporating a FeCoCrNiAl alloy powder layer, enabling efficient harvesting of low‐frequency mechanical energy. The quasi‐enclosed conductive architecture mimics a Faraday cage, effectively confining electrostatic charges and suppressing edge‐induced dissipation, thereby enhancing charge retention. Compared to single‐metal triboelectric layers, the FC‐TENG exhibits 4.86‐, 3.57‐, and 2.76‐fold increases in open‐circuit voltage ( V OC , 1276.27 V), short‐circuit current ( I SC , 63.69 μA), and transferred charge ( Q…
