AI Technical Summary

Technical Problem

Existing flexible tactile sensors are prone to damage to their internal pressure-sensitive elements and signal processing circuits when subjected to pressure exceeding their design range, leading to performance degradation or failure. This results in high equipment maintenance costs, impacting production efficiency and reliability, especially in scenarios such as industrial automation and warehousing logistics.

Method used

The shielding layer is composed of a metal braided mesh and flexible insulation material, a flexible board made of polymer material, a protective layer made of polyurethane material, and rigid corner sleeves and roller shaft design. This constructs a comprehensive pressure-resistant protection system, disperses stress concentration, transforms friction mode, and enhances electromagnetic shielding for connection stability and signal transmission.

Benefits of technology

It significantly improves the sensor's pressure resistance and service life, ensuring stable operation under high pressure and strong impact environments, reducing wear and electromagnetic interference, and improving signal accuracy and equipment reliability.
