摘要
As a renewable clean energy with good application prospects, wind energy has attracted more and more attention. Harvesting energy from the ambient environment with triboelectric nanogenerators (TENGs), for use in electronic devices has become a feasible method. Nevertheless, the alternating‐current signal generated by TENGs needs to be converted into direct‐current signal to be effective in applications. Therefore, this article presents a power management circuit with a self‐triggering triboelectric‐electromagnetic hybrid generator (ST‐TEHG). The switch module of the power management circuit is composed of an electromagnetic (EMG), 555 single timer, and an N‐type metal–oxide–semiconductor, the module converts the AC signal output by EMG into a square wave signal under monostable state. The self‐triggering switching function is realized when in monostable operation. Systematic experiments demonstrate that the 555 single timer function can output waveforms of monostable operation. The back‐end of the circuit can output DC signals stably, the ripple voltage is 0.03 V, and the ripple coefficient is 0.52%. ST‐TEHG provides a new way of thinking for the power supply of microelectronic components.
