WIRELESS CONTACT FORCE SENSING AND LOCALIZATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18554726 titled 'WIRELESS CONTACT FORCE SENSING AND LOCALIZATION

Simplified Explanation: The wireless force sensor described in the patent application consists of a flexible structure and a rigid structure with a gap between them. Contact traces on the surfaces of these structures form transmission lines that are modulated by radio-frequency switches. An antenna sends an interrogation signal and receives the reflected signal from the transmission lines.

• Contact traces on flexible and rigid structures form transmission lines
• Radio-frequency switches modulate the signal from the transmission lines
• Antenna sends interrogation signal and receives reflected signal
• Flexible structure supported by rigid structure with a gap between them
• Contact between traces occurs when force is applied to the flexible structure

Original Abstract Submitted

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.
