From: A bioinspired flexible neuromuscular system based thermal-annealing-free perovskite with passivation
a EPSC triggered by 100 consecutive spikes (−0.5 V, 68 ms) in perovskite artificial synapse with/without PEAI passivation. b EPSC triggered by 2000 consecutive spikes (−0.5 V, 68 ms) in perovskite artificial synapse with/without PEAI passivation. c Logical operations in perovskite artificial synapse with PEAI passivation. d, e Schematic diagram of spatiotemporal-correlation signal-processing in organisms and RT-PVK artificial synapses. f EPSC versus interval ΔT between spike 1 and spike 2 (ΔT < 0: spike 2 after spike 1; ΔT > 0: spike 1 after spike 2). g Conditional reflex learning in perovskite artificial synapse with PEAI passivation.
