), long-term environmental stability (≥8 months), and excellent mechanical bending performance (600 bending cycles). The synaptic plasticity in the device is also verified, including paired pulse facilitation (PPF) and spike-timing-dependent plasticity (STDP). By applying resistance memory characteristics, the memristor achieves fear emulation, enabling the realization of key characteristics including "self-extinction", "generalization", and "avoidance". Finally, sound perception is simulated via imposing different signals controlled by different voltage parameters (frequency and amplitude) and light illuminance. Sound characteristics including "pitch", "loudness" and "timbre" are successfully determined. Our work proposes a new application avenue for lead-free flexible perovskite memristors in multimodal intelligent perception and biological simulation.
