Non von Neumann Multi-Input Spike Signal Processing Enabled by an Artificial Synaptic Multiplexer

Multiplexing is essential for technologies that require processing of a large amount of information in real time. Here, we present an artificial synaptic multiplexing unit capable of realizing parallel multi-input control system. Ion-gel was used as a dielectric layer of the artificial synaptic multiplexing unit because of its ionic property, allowing multi-gating for parallel input. A closed-loop control system that enables multi-input-based feedback for actuator bending control was realized by incorporating an ion-gel-based artificial synaptic multiplexing unit, actuator, and a bending angle sensor. The proposed multi-input control system could simultaneously process input and feedback signals, offering a breakthrough in industries in which the processing of vast amounts of streaming data is essential.
