Hybrid Force Radiometric Array with Direct Analog Force-to-RF Conversion

Brief Description

This technology introduces a novel approach for bridging force sensing with wireless communication through direct analog force-to-RF conversion provides lower power consumption and lower costs.

Full Description

This innovative design combines a thin-film force sensor array, a flexible printed circuit board (PCB), class-D voltage-controlled oscillators (VCOs), and a multiport loop antenna to convert force directly into radio-frequency (RF) signals. Aimed at reducing power consumption while increasing the dynamic range and resolution of force measurements, this system facilitates robust wireless connectivity over distances greater than 5 meters, making it suitable for a variety of applications in robotics, healthcare, automotive, and aerospace industries.

Suggested uses
