AI Technical Summary
Technical Problem
The existing pressure-sensitive layer is prone to wrinkles during the manufacturing process, which affects the performance of the smart pad.
Method used
The first and second base layers are connected by ultrasonic welding. By distributing ultrasonic welding parts at intervals along a certain direction on both sides of multiple conductors, the lateral pulling of the nonwoven fiber layer is avoided, the generation of wavy wrinkles is prevented, and pressure sensing is achieved through conductive carbon film material.
Benefits of technology
It improved the product's appearance quality and overall stability, enhanced the structural strength and reliability of the sensing layer, reduced production costs, and improved production efficiency and user experience.
