Abstract
A device and associated method for adjusting electrical impedance based on contact action are disclosed. The device includes a drive unit (), a contact unit (), a monitoring unit (), and a control unit (). The monitoring unit () measures an impedance signal of an electromagnetic functional material () in an alternating-current circuit, and transfers the impedance signal to the control unit (). In response to the impedance signal measured by the monitoring unit (), the control unit () controls the drive unit () to apply a mechanical load on the contact unit (), which causes the contact unit () to contact the electromagnetic functional material (). The value of a contact load is adjusted, so as to adjust the electrical impedance of the electromagnetic functional material (), thereby achieving the objective of adjusting the impedance matching in the alternating-current circuit in real time.
