Abstract
Integration of electromagnetic generators (EMGs) and triboelectric nanogenerators (TENGs) can increase the total energy conversion efficiency from one mechanical motion by connecting the two devices in parallel after using power management circuits. A critical issue is how to realize the integration of the EMG and TENG in the same current circuits. Here, a hybridized nanogenerator, including an EMG and a TENG with the same set of electrodes, has been utilized to simultaneously scavenge mechanical energy. The hybridized nanogenerator can deliver a high output current of about 3.8 mA and a high output voltage of about 245 V when the switch in the device circuit was turned on and off, respectively. A acceleration sensor can be achieved by using the hybridized nanogenerator, where the detection sensitivities are about 143.2 V/(m/s(2)) for TENG and 291.7 μA/(m/s(2)) for EMG. The fabricated hybridized nanogenerator may have practical use for scavenging mechanical energy and self-powered acceleration sensor systems.
