Triboelectric nanogenerators (TENGs) can convert the mechanical energy of physical activities into electricity. This is particularly useful in sports applications, where activity power devices such as wearables that provide real-time feedback on athletes’ performance or health. To work, a TENG usually needs tribopositive and tribonegative materials. Currently, vast majority TENGs use materials containing perfluoroalkyl polyfluoroalkyl substances (PFAS) However, these pose risks to humans environment, which has led European Union consider restrictions compounds. For this reason, PFAS-free alternatives, polydimethylsiloxane (PDMS) MXenes, need be better explored replace PFAS while aiming achieve equal efficiency. review will explore some recent advances have been developed field TENGs, with an emphasis applications.
