AI Technical Summary
Currently, no PVDF film has been applied to texture tactile perception, especially for detecting the micro-tactile sensation and uneven features of object surfaces, which cannot meet the high-realism human-computer interaction requirements of wearable devices and virtual reality.
A texture tactile sensor was designed, which combines a PVDF film with an insulating layer and an epoxy resin layer. The sensor is installed inside a housing and connected to a data card or control panel via external leads and wires. It utilizes the piezoelectric properties of the PVDF film to sense the micro-tactile sensation and uneven features of the object surface and is easy to install in the area to be measured using a mounting bracket.
It achieves efficient and accurate texture perception, capable of detecting the micro-tactile sensation and uneven features of object surfaces. It is applicable to fields such as virtual reality, augmented reality, medicine, and robotics, providing high-resolution and real-time texture touch acquisition, and has good application prospects.
