Highly Reliable and Sensitive Tactile Transistor Memory

摘要

Keeping the information arising from tactile stimulation, such as pressure and texture of objects, is an essential feature for artificial intelligence. This important characteristic is intimately related to physiological behavior in daily activities. In order to develop next‐generation electronic skin for biomimetic prosthetics, repeating the history of a tactile motion is a must‐have function. Here, the first environmentally friendly, low‐cost, and multifunctional device is reported, which can act as a pressure sensor, transistor, as well as memory. This tactile transistor memory is very sensitive to external pressure and can store the pressure information after removing the external stimuli for subsequent manipulation. This work is a key step for the future development of intelligent robotic systems with learning capability.
