Human skin is the complex of many highly developed prosthetics and sensors. In recent studies, the development of the tactile interface aims to mimic the biological behavior of tactile receptors for sensory feedback. Neuromorphic tactile interface implements components of the nervous system, such as touch expression through spike activity, based on biological models. Herein, we describe a novel design of a synaptic tactile transistor based on a hydrogen-triggered mechanosensitive ion channel layer that selectively responds to pressure stimulus. The ion channel enables tactile sensing and modulation of synaptic plasticity in a monolithic structure. The synaptic tactile transistor has high sensitivity due to the electrochemically doped multi-level channel conductance originated from the change in ion concentration by pressure stimuli. Consequently, we believe that novel material design will provide new insight into developing synaptic electronics for neural prosthetics and soft robotics. |
