Abstract | The invention discloses a non-inductive piezoelectric energy collection circuit, an energy collection method and a zero-cross detection circuit. The non-inductive piezoelectric energy collection circuit comprises a charge overturning main circuit, the zero-cross detection circuit, a state judgment circuit, a pulse signal circuit and a pulse sequencing circuit, the beneficial effects of the invention are that when micro-electronic equipment is used to collect weak vibration energy in an environment, a simpler structure is adopted to improve and optimize an existing non-inductive energy collection technology based on a synchronous switch; a more accurate zero-cross detection circuit in a sampling resistor mode is adopted, so that the accuracy of the detection circuit is improved; a simple pulse signal circuit is designed by using fewer digital logic circuit elements, so that the system loss is reduced, the circuit work is more efficient, and the system volume is smaller.
