Title:
HIGH-SENSITIVITY INSTANTANEOUS SELF-POWERED WIRELESS SENSING SYSTEM OF FRICTIONAL NANO-POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2023/035591
Kind Code:
A1
Abstract:
Disclosed in the present invention is a high-sensitivity instantaneous self-powered wireless sensing system of a frictional nano-power generator. The output ends of the frictional nano-power generator are directly connected to the input ends of a controller; the output ends of the controller are respectively connected to the input ends of a transmitting module, and the transmitting module is wirelessly connected to a receiving module; in the controller, the two ends of a peak voltage detector (PVD) are connected between the two input ends of the controller; the PVD is connected to the gate of an MOS transistor Q1; the MOS transistor Q1 and one end of the PVD are connected and grounded; and the MOS transistor Q1 is connected to the other end of the PVD after sequentially passing through a bidirectional voltage-stabilizing diode ZD and a diode D1, and the two output ends of the bidirectional voltage-stabilizing diode ZD are used as the two output ends of the controller. The present invention can greatly enhance the stability of the amplitude and frequency of a transmitting signal, and enhance the anti-interference capability of a sensing system.
