A Stable and Durable Triboelectric Nanogenerator for Speed Skating Land Training Monitoring

In the current IoT era, key to sports intelligence is effective collection and analysis of data. Sports data can accurately reflect an athlete’s athletic status help coaches develop competitive tactics training programs. Wearable electronic devices used collect currently have several drawbacks, including their large size, heavy weight, complex wiring, high cost, need for frequent power replacement. this work, transparent polyamide-66 (PA-66) polytetrafluoroethylene (PTFE) films were as friction layers, polydimethylsiloxane (PDMS) was a support layer, conductive hydrogels electrodes, which simply combined create stable durable triboelectric nanogenerators (SD-TENG) with good mechanical properties. test, output 1mW under load resistance 10MΩ. addition, integrated intelligent speed skating land assistance system monitors changes in joints joint chains skaters during real time. The successful demonstration use SD-TENG will promote development application TENG fields sport monitoring, smart wearable devices, big analysis.
