摘　　要：Artificial multisensory devices play a key role in human-computer interaction in the field of artificial intelligence(AI).In this work,we have designed and constructed a novel olfactory-visual bimodal neuromorphic carbon nanotube thin film transistor(TFT)arrays for artificial olfactory-visual multisensory synergy recognition with a very low power consumption of 25 aJ for a single pulse,employing semiconducting single-walled carbon nanotubes(sc-SWCNTs)as channel materials and gas sensitive materials,and poly[[4,8-bis[5-(2-ethylhexyl)-2-thienyl]benzo[1,2-b:4,5-b0]dithiophene-2,6-diyl]-2,5-thiophenediyl-[5,7-bis(2-ethylhexyl)-4,8-dioxo-4H,8H-benzo[1,2-c:4,5-c0]dithio-phene-1,3-diyl]](PBDB-T)as the photosensitive material.It is noted that it is the first time to realize the simulation of olfactory and visual senses(from 280 nm to 650 nm)with the wide operating temperature range(0-150℃)in a single SWCNT TFT device and successfully simulate the recovery of olfactory senses after COVID-19 by olfactory-visual synergy.Furthermore,our SWCNT neuromorphic TFT devices with a high IOn/IOff ratio(up to 10^(6))at a low operating voltage(−2 to 0.5 V)can mimic not only the basic biological synaptic functions of olfaction and vision(such as paired-pulse facilitation,short-term plasticity,and long-term plasticity),but also optical wireless communication by Morse code.The proposed multisensory,broadband light-responsive,low-power synaptic devices provide great potential for developing AI robots to face complex external environments.
