Zusammenfassung: | The invention discloses a frictional electricity-based vibration signal measurement method, which comprises the following steps that: a lower electrode layer, an independent layer and an upper electrode layer are sequentially arranged on a vibration source, the independent layer comprises a plurality of negatively charged friction dielectric mediums, and the friction dielectric mediums move between the upper electrode layer and the lower electrode layer through external vibration to form three electric fields E1, E2 and E3; the potential difference between the upper electrode layer and the lower electrode layer is calculated according to the three electric fields, the transferred charge quantity is calculated according to the movable distance of the friction dielectric between the upper electrode layer and the lower electrode layer, a power generation equation capable of achieving the minimum charge reference state is constructed according to the potential difference and the transferred charge quantity, and t |
