Abstract
A wireless force sensor includes a flexible structure supported opposing a rigid structure with a gap between the flexible structure and the rigid structure. Contact traces on opposing surfaces of the flexible structure and the rigid structure form transmission lines. The contract traces are aligned to contact when a force is applied the flexible structure to cause contact between the traces on the opposing surfaces. Radio-frequency switches modulate a reflected signal from the transmission lines. An antenna receives an interrogation signal transmits the reflected signal.
