With the aim to developing an artificial intelligence and a deep learning technologies, many attempts have been made to mimic sensory-motor nervous system for future applications, such as neurocomputing, humanoid robots, and neural prosthetics. In particular, to emulate the sensory system of human, researchers have reported the integrated systems composed of three devices: sensor, signal transducer, and synaptic transistor. However, they show poor device density and complicated signal conversion. Here, we describe a novel artificial synaptic transistor inspired by human sensory system, which have sensing ability and synaptic behavior that can be triggered by mechanical stimuli. We designed an ionic composite with hydrogen bonding as a dielectric layer, in which capacitance could be switched under only mechanical stimuli. As a result, mechanically triggered synaptic transistor exhibited various forms of synaptic plasticity with amplitude and frequency of pressure as a presynaptic pulse. |
