From: A bioinspired flexible neuromuscular system based thermal-annealing-free perovskite with passivation
a EPSC triggered by a pair of spikes (−0.5 V, 68 ms) in perovskite artificial synapse with/without PEAI passivation. b PPF index versus time interval in perovskite artificial synapse with/without PEAI passivation. c SDDP behaviour of the device. EPSC triggered by consecutive spikes with different durations (d1 = 68 ms, d2 = 136 ms, d3 = 545 ms, d4 = 615 ms) and the same voltage amplitude (−0.5 V) in RT-PVK artificial synapse with or without PEAI passivation. Black: voltage spikes; pink and orange: response currents of the devices. d SRDP behaviour of the device. Frequencies f1 = 1.06 Hz, f2 = 6.39 Hz. Each group consisted of 10 spikes (−0.5 V, 68 ms) e EPSC triggered by spikes at varied voltages (−1 to −1000 mV). f Cycles of potentiation and depression in perovskite artificial synapse with PEAI passivation.
