Conventional logic operations transmitting data between processing and the memory unit inevitably result in a "memory wall" energy consumption dilemmas. The memristor provides an alternative solution at device level by integrating functions, however, combination of multistage memristors is required to achieve fundamental Boolean calculations, especially for XOR/XNOR. In this work, we implement XOR/XNOR through leveraging bifunctional oxygen-containing Ti thin films as both current collectors Li-reservoirs two-terminal Li-based memristor, i.e., ITO/Nb2O5/LiCoO2/Ti. When Li-ions are inserted into under reversed voltage partially reduce high-valence Ti, subsequent postsynaptic exceeds threshold, thereby realizing operations. Therefore, entire seven can be achieved individual device, featuring biological-like synaptic plasticity without redundant circuit design. Through electrochemical modulation pulse parameters, artificial synapse demonstrates versatile types short-term potentiation, encompassing pair-pulse facilitation, spike-voltage-dependent plasticity, spike-rate-dependent-plasticity (SRDP). SRDP displays properties analogous high-pass filter discernible distinction response within beyond frequency 1 Hz. Furthermore, Physiological functions Ebbinghaus' curves Pavlov's classical conditioning experiment emulated on single based principles long-term potentiation.

Abstract Artificial skin should embody a softly functional film that is capable of self-powering, healing and sensing with neuromorphic processing. However, the pursuit bionic combines high flexibility, self-healability, zero-powered photosynaptic functionality remains elusive. In this study, we report self-powered self-healable vision skin, featuring silver nanoparticle-doped ionogel heterostructure as photoacceptor. The localized surface plasmon resonance induced by light in nanoparticles triggers temperature fluctuations within heterojunction, facilitating ion migration for visual synaptic behaviors. abundant reversible hydrogen bonds endow remarkable mechanical flexibility self-healing properties. We assembled equipped 5 × photosynapse array, memorizing diverse patterns.
