摘 要:Triboelectric energy harvesters offer an efficient way to convert mechanical energy harvested by every-day human body actions into electrical *** nanogenerators(TENGs)are an attractive solution for power supply concerns in the development of portable electronic gadgets and self-powered sensor ***,a dielectric calcium copper titanate(CaCu_(3)Ti_(4)O_(12)(CCTO))ceramic material was synthesized by a solid-state reaction *** synthesized particles were embedded in poly-dimethylsiloxane(PDMS)polymer to form a CCTO/PDMS flexible composite film(FCF)-based TENG,called a CCTO FCF-TENG,which is light-weight,simple,and suitable for *** dielectric properties,surface charge density,and electrical conductivity of the FCF were greatly improved by the addition of the CCTO particles into the PDMS,resulting in excellent electrical output performance of the corresponding CCTO *** CCTO FCF-TENG device was constructed with the CCTO/PDMS FCF,which functioned ver-tically against a cellulose paper to optimize a high and stable electrical ***,the filler concentration and film thickness optimization was studied more to achieve the highest output power of the CCTO *** optimized CCTO FCF-TENG exhibited the highest electrical output voltage,cur-rent,charge density,and power density of-250 V,-6.5μA,-70μC/m^(2),and-3.15 W/m 2,*** mechanical stability and durability of the CCTO FCF-TENG were systematically *** practical and real-time applications of the packed CCTO FCF-TENG were systematically investigated under various harsh environmental ***,the packed CCTO FCF-TENG successfully powered several low-power portable electronics and was also used as a self-powered sensor to sense biomechanical actions in everyday human body activities.
