摘要
基于电压刺激诱导信号转换的电子技术是现代先进智能设备、工具和仪器的核心基础之一.然而,此类转换仅由外加电压刺激引起,导致其信号输出一般为二进制,难以满足众多新兴前沿应用场景的需求.在此,我们开发了一种由二维还原氧化石墨烯/聚吡咯(rGO/PPy)构成的有序共轭体系,并利用其电学各向异性构建了可响应多种刺激的信号适配器.rGO/PPy的准二维几何结构产生的电学各向异性确保了设备能够在不同刺激下产生不同类型的电信号.通过对光和压力输入(除了电压之外的两种最常见输入刺激)的有效识别,该信号适配器实现了四进制/十进制信号和可视化光信号的输出,并进一步实现了基于无源器件的信息加密.此外,该信号适配器在多次压力/光刺激过程中展现出高循环稳定性.这种低成本、便于大规模生产的信号适配器开启了新一代智能系统构建的大门,并有望推动人机交互、电子皮肤、生物植入设备等领域的发展.
Abstract
Electronic technology,based on signal conver-sion induced by voltage stimulation,forms the core founda-tion of the state-of-the-art intelligent devices,tools,and equipment.Such conversions are inherently binary and lim-ited because they rely solely on voltage,which presents chal-lenges for many emerging frontier applications.Here,a two-dimensional ordered conjugated system of reduced graphene oxide/polypyrrole(rGO/PPy)has been developed.Multi-sti-mulus response signal adapters have been constructed,uti-lizing the electrical anisotropy inherent in the rGO/PPy system.This electrical anisotropy,derived from the quasi-two-dimensional geometry of rGO/PPy,enables the device to produce distinct electrical signals in response to various sti-muli.With effective responses to light and pressure,the two most common input stimuli other than voltage,it can output quaternary/denary signals and visual optical signals,as well as enables information encryption using passive devices.Fur-thermore,the signal adapter demonstrates high cyclic stability under repeated pressure and/or light loading.The successful development of this low-cost,scalable signal adapter paves the way for the next-generation of intelligent systems,promising advancements in human-computer interaction,electronic skin,biological implant equipment,and related fields.
