Bioinspired sweat-resistant wearable triboelectric nanogenerator for movement monitoring during exercise

Regular exercise plays an important role in remedying body suboptimal health status and releasing daily stress. Herein, we proposed a bioinspired sweat-resistant wearable triboelectric nanogenearator (BSRW-TENG) for movement monitoring during exercise. The BSRW-TENG consists of two superhydrophobic self-cleaning layers (elastic resin polydimethylsiloxane (PDMS)), which featured the hierarchical micro/nanostructures replicated from lotus leaf. not only realized 2-fold output increase BSRW-TENG, but also offered with excellent contamination humidity resistant properties that constitute sweat-resistance. After saline (0.9%) dripped on evaporated, remained same while flat-TENG decreased by 41% due to salt surfaces. Besides, demonstrated humidity-resistance 11% reduction as relative increased 10% 80%, 54%. ability was further verified under extreme harsh conditions including complete surface ultra-humid water spraying. Finally, various movements dumbbell biceps curl, leg curl running were successfully monitored stable performance before after sweating. has huge potential low-cost personal athletes’ training analysis.
