Abstract

Abstract: The bio-memristor based on biomaterial has ushered in enthusiasm and optimism in brain-inspired computing systems. Here, the bio-memristor based on sericin has been fabricated with the structure of Ag/sericin/W. The sericin-based bio-memristors demonstrated threshold-switching behavior with low set voltage (∼0.25 V), good cycle-to-cycle uniformity (∼400 cycles), and a large switching window (>100). Interestingly, the device conductance was tuned gradually by the modulation of voltage pulses (amplitude, number, and frequency). The synaptic behaviors can be mimicked, i.e., short-term plasticity, spike-rate-dependent plasticity, and spike-timing-dependent plasticity. This work may open new avenues of bio-memristors in brain-inspired neuromorphic systems.
