AI Technical Summary

Technical Problem

Existing flexible multi-axis force sensors are difficult to achieve six-dimensional force/torque measurement and suffer from signal crosstalk and structural complexity, which limits the application scenarios of traditional rigid six-dimensional force/torque sensors.

Method used

A flexible six-dimensional force/torque sensing device based on U-shaped micro-nano optical fibers is adopted. By combining four U-shaped micro-nano optical fibers with a flexible elastomer, the photoelastic effect and anisotropy are utilized to realize the measurement of six-dimensional force/torque, reducing crosstalk and coupling.

Benefits of technology

It improves sensitivity and measurement accuracy, enabling accurate measurement of six-dimensional force/torque, and is suitable for fields such as flexible robots, flexible electronic skin, and health and medical monitoring. It is also electrically passive and biocompatible.
