Description

technical field [0001] The invention relates to the field of electronics, in particular to an information acquisition method, equipment and capacitor. Background technique [0002] In the prior art, when measuring the distance between the hand and another conductor (such as a copper sheet), it can be realized by measuring the capacitance value between them. [0003] But when measuring the capacitance value between them, the measurement result is often unstable. For example, if the distance between the hand and the copper sheet is 8cm, the capacitance value measured at this time is 30pf. If the distance between the hand and the copper sheet does not change and the measurement continues, the capacitance value measured for the second time may change. into 50pf, if the measurement is performed again, different results may be obtained. This makes it difficult to obtain the exact distance between the hand and the copper sheet based on the measured capacitance value. Contents o...
