Abstract
A strain sensor includes a flexible substrate and a circuit disposed on the flexible substrate. The circuit includes an inductance to receive an excitation signal, the circuit being configured to generate a radio frequency response to the excitation signal via the inductance. The circuit includes an elongated trace coupled to the inductance and configured to bend and stretch longitudinally upon deformation of the flexible substrate. The elongated trace includes a non-uniformity configured such that the elongated trace deforms and tears at the non-uniformity and exhibits a non-linear increase in resistance as a tensile strain to which the elongated trace is subjected reaches a strain threshold. The non-linear increase in resistance modifies a characteristic of the radio frequency response of the circuit.
