Fabrication of high-performance triboelectric nanogenerator based on NiC nanosheets to self-power thermal patch for pain relief.

In this work, we report a vertical contact-separation mode triboelectric nanogenerators (TENG) comprising of NiC/PDMS composite and Nylon Nanofibers for self-powering a nichrome wire-based thermal patch for muscular/joint relaxation. An optimised composition of NiC (25 wt%) and PDMS as a tribo-negative material and Nylon Nanofibers synthesised via electrospinning on copper electrode foil as a tribo-positive material were used to fabricate the TENG. The fabricated TENG exhibits outstanding output generating an average open circuit voltage of ∼252 V, an average short circuit current of ∼40.
