RF-Tactrix: Fingerprint-Inspired Battery-Free, Wireless Force Sensing And Localization on 2D Surfaces

摘要

Accurate sensing and localization of surface force are crucial in various applications, including muscle rehabilitation, robotic manipulation of fragile objects, and finger rehabilitation training. However, existing technologies struggle to achieve high-precision and continuous force sensing, due to the crosstalk interference from dense sensor arrays or ambient light interference from optical sensors or reliance on batteries and power-hungry components.
