A triboelectric nanogenerator based on CNC/gelatin for running and jumping training monitoring
Source abstract
Abstract
In this work, we proposed a triboelectric nanogenerator (TENG) based on cellulose nanocrystal (CNC)/gelatin composite film (CG-TENG) to monitor the posture and movements of athletes during jumping training. The triboelectric layers comprise a polytetrafluoroethylene film (which carries a negative charge) and a CNC/gelatin composite film (manifesting a positive charge). The CNC is derived from recycled wasted boxes using the traditional sulfuric acid hydrolysis method and is incorporated into the gelatin film as a nanoscale additive. By utilizing an external load resistance measuring 20 MΩ, it is possible to attain an all-time high instantaneous power of 583 µW. The electrical output of the CG-TENG demonstrates notable stability and endurance, as it maintains a consistent pattern during a duration of more than 30 000 cycles. By capitalizing on sustainable and green materials, the CG-TENG paves the way for innovative sports monitoring solutions, amplifying the potential for human physiological signal tracking.
