Key surface modification strategies, such as termination group control, defect regulation, heteroatom doping, and oxidation tuning, are discussed in relation to their influence on the work function, conductivity, and chemical reactivity.

Similarly, agricultural and food waste, produced in large quantities, also imposes considerable disposal and processing costs. Addressing both of these issues, this study explores the potential of creating environmentally friendly electronic materials from renewable resources derived from agricultural byproducts. Specifically, sustainable electronic conductors are developed by converting tomato plant waste into conductive, biodegradable materials. This is achieved by integrating graphene nanoplatelets (GnPs) with hydrolyzed tomato waste in bio-based latex matrices using water-based methods. Importantly, the use of hydrolyzed tomato waste without the need for isolating specific components represents a whole-biomass utilization strategy. This approach simplifies processing while maximizing the valorization of agricultural waste. The resulting latex–tomato waste composite containing 20 wt.% GnPs exhibits satisfying mechanical properties and moisture resistance, along with a resistivity of 0.46 Ω · m. Notably, it serves effectively as an electrode for recording the bioimpedance of fruits. These findings demonstrate the potential of this material as a sustainable alternative for green electronics, while simultaneously contributing to the reduction of both electronic and agricultural waste within a circular economy framework.</p>","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"11 14","pages":""},"PeriodicalIF":5.3,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aelm.202500109","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many biological processes rely on out-of-equilibrium, often oscillatory, ionic fluxes that do not involve chemical reactions. Examples include action potentials in neurons, muscle contraction, cardiac rhythmicity, intracellular calcium signaling, and calcium wave oscillations. Despite these parallels, the development of biomimetic systems compatible with neuromorphic interfaces remains a significant challenge. Here, a strategy is demonstrated to organize oscillating ionic currents by developing ionic transistors composed of graphene oxide and polyelectrolyte, and assembling them into all-ionic integrated circuits. By driving these systems out of equilibrium using external voltages, periodic motion of various ions across defined interfaces is achieved. This behavior, governed by local electric fields arising from unbalanced ionic concentrations, closely mimics biological excitability, such as that observed in neuronal and cardiac systems.
