Micron-level flexible array tactile sensor - RXCJ1A-1

I. Product Introduction

This is an "electronic skin" designed specifically for robots—a conformable, bendable flexible sensing film that can convert pressure distribution on the contact surface into a high-resolution digital signal matrix in real time, giving robotsTactile perception and force feedback capabilities comparable to human fingertips。

In the technological evolution of robots from "seeing" to "touching," this sensor addresses exactlyTactile sensingthis core bottleneck. Whether it is the precise grasping of dexterous hands or the safe interaction of collaborative robotic arms, it relies on this to sense "how much force was used," "what shape was contacted," and "whether slipping occurred."

 

II. Working principle

1. Physical deformation:External force acts on the surface, causing microscopic deformation of the internal microstructure.

2. Impedance modulation:The contact area or pathway of the sensitive conductive layer changes, causing resistance to change.

3. Signal acquisition:Orthogonal electrode layers precisely capture resistance changes at each pixel.

4. Tactile imaging:Peripheral circuits convert to high-resolution "tactile heat map".
