Transient Security Transistors Self-Supported on Biodegradable Natural-Polymer Membrane for Brain-Inspired Neuromorphic Applications

Abstract

Transient electronics, a new generation of electronics that can physically or functionally vanish on demand, is very promising for future “green” security biocompatible electronics. At the same time, hardware implementation of biological synapses is highly desirable for emerging brain-like neuromorphic computational systems that could look beyond the conventional von Neumann architecture. Here, hardware-security physically-transient bidirectional artificial synapse network based on dual in-plane-gate Al-Zn-O neuromorphic transistor is fabricated on free-standing laterally-coupled biopolymer electrolyte membranes (sodium alginate). Excitatory postsynaptic current, paired-pulse-facilitation, and temporal filtering characteristics from high-pass to low-pass transition are successfully mimicked. More importantly, bidirectional dynamic spatiotemporal learning rules and neuronal arithmetic are also experimentally demonstrated by using two lateral in-plane gates as the presynaptic inputs. Most interestingly, excellent physically-transient behavior can be achieved with a superfast water-soluble speed of only ~120 seconds. This work represents a significant step towards future hardware-security transient biocompatible intelligent electronic systems.
