Abstract: Inspired by the brain computing mode, significant efforts have been dedicated to developing neuromorphic devices to realize energy-efficient neuromorphic systems . Specifically, a neuron can deal with spatiotemporal input patterns with dendrites, meaningful for multi-modal responses of our perceptual system. Here, a multi-gate blended polyvinyl alcohol/chitosan based electrolyte gated oxide dendrite transistor was fabricated. With extremely strong interfacial protonic/electronic coupling, the proposed dendrite transistors exhibit rich neuromorphic functions under heterosynaptic mechanism. Spatiotemporal dendritic integration and linear/nonlinear dendritic algorithms were demonstrated, showing its versatility in complex bionic neuronal processes. Logic operations were successfully implemented, including “OR”, “AND”, “NOR”, “NAND”. Capacitively coupled multi-terminal oxide dendrite transistors are also proposed for data classification and information decoding. Finally, neural addition operation was realized on a single dendrite transistor. These results indicate that the present neuromorphic devices could be building blocks for neuromorphic systems, offering an interesting strategy toward efficient and compact neuromorphic architectures.
