Here, we propose an energy-efficient neural device based on natural cellulose, addressing limitations in conventional interface communication hardware, particularly concerning material biocompatibility and biological signal matching. The cellulose-based device effectively emulates the plasticity of biological synaptic connections and exhibits learning behavior under biograde voltage as low as 10 mV. Significantly, it demonstrates exceptional digital-to-analog conversion performance with a minimal power consumption of 0.1 nJ, facilitating efficient interface biological signal matching. Furthermore, a molecular-level model is introduced to elucidate the rotation of intramolecular polar bonds in cellulose induced by electrical stimulation. This rotation alters the material’s relative dielectric constant, unveiling the digital-to-analog conversion ability and neuro-like behavior. The biocompatible cellulose-based device efficiently emulates synapses with its low-power signal conversion, holding promise for effective biological signal matching in brain–machine interfaces.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":11.4,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141935177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
