摘      要：Body area network has attracted extensive attention for its applications in athletics,medical,diagnosis,and rehabilitation training in the next generation personalized health care ***,a contact-separation direct current triboelectric nanogenerators(CSDC-TENGs)based selfpowered wireless body area network(SWBAN)is reported that enables multi-joint movements monitoring for human *** CSDC-TENG is designed as a flexible active sensor with an internal contact switch,and the flexible substrate makes the TENG-sensor stick onto skin *** to the internal switch,the CSDC-TENG could generate a DC current,a large instantaneous output voltage exceeds 700 V,and an instantaneous power can reach 1.076 W,which is more than 23000 times higher than that of the traditional contact-separation mode TENG in same size and materials without the *** coupling with flexible coil,the fixed high-frequency radio signals can be modulated and emitted clearly ranging from 6 to 16 MHz,which can be wirelessly received and demodulated through a ***,the SWBAN is demonstrated in a real time monitoring system for joints *** work has realized the wearable TENG for self-powered wireless real-time monitoring of body movements driven by low-frequency human daily activities,which may promote a tremendous development of intelligent healthcare,wireless sensing system and body area network.
