Development is based on the triboectric effect. The sensor consists of two main parts: external, responsible for the determination of materials and fixes the pressing power and direction. Special electrodes are made to the silicone shell and the internal structure contains microscopic needles and conductive elements that respond to touch.
During the tests, the sensor successfully identified the direction of the applied force and was accurately recognized by 12 materials that were common in daily life. The accuracy in the definition was more than 98%.
It was built on a robotic hand to control the device. Real -time sensor to analysis platforms such as labview and jupyter, which allows the robot to determine and respond to touch.
