A circuit is provided that includes a strain gauge resistor having a center axis and multiple conductor layer segments and a trim region extending along the center axis; wherein a first portion of the strain gauge resistor is located on one side of the center axis and a second portion of the strain gauge resistor is located on an opposite side of the center axis.

A circuit is provided that includes a strain gauge resistor having a center axis and multiple conductor layer segments and a trim region extending along the center axis; wherein a first portion of the strain gauge resistor is located on one side of the center axis and a second portion of the strain gauge resistor is located on an opposite side of the center axis.

An element includes an upper electrode, a flexible intermediate layer, and a lower electrode. The upper electrode having an uneven structure. The lower electrode is closely attached to the intermediate layer. The element is configured to generate an electrical signal due to contact and separation between the upper electrode and the intermediate layer. The lower electrode is configured to take a shape fittable to the uneven structure when the upper electrode and the intermediate layer come into contact with each other.
