The photoresponvity of MoS2 phototransistors ranges from 1$0^{-4}$ to 104 mA/W by modulating gate voltages, emulating the synaptic weights in a neural network. Based on this sensor, we construct an in-sensor SNN and successfully perform a lane keeping task in an event-driven manner. Instead of sensing and generating the spike signals of all pixels, our design saves 97% data by only processing the local pixel with the change of light intensity. When an event is triggered (light intensity changes from 1.6 to 5.1 mWc$mathrm{m}^{-2}$), each pixel realizes event-based sensing and processing simultaneously with ultralow power consumption (160nW), showing the potential for energy-efficient edge intelligence.","PeriodicalId":275494,"journal":{"name":"2022 International Electron Devices Meeting (IEDM)","volume":"48 30","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120889048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
