description With the demand of wearable device in the field of flexible electronic, synaptic devices with capability of neuromorphic computing are attracting increasing attention. In this paper, an organic flexible device with excellent synaptic behaviors was fabricated on MICA substrate, which has a memory window more than 20V. Furthermore, the device simulates organism synaptic behaviors successfully, such as paired-pulse facilitation (PPF), long-term potentiation/depression (LTP/LTD) process and transition from short-term memory (STM) to long-term memory (LTM) by optical and electrical modulation. Importantly, after repeated bending, the electrical characteristics of the device maintains stable and can still obtain synaptic behaviors by electrical and optical pulses. The proposal of the device provides the possibility of applications for wearable artificial synapses.
