Alternating Current Electroluminescent Humidity-sensitive Visualized Film Sensor Driven by Body Coupling
摘要
Abstract
With the rapid development of wearable electronics,intelligent sensing,and flexible interactive technologies,human-machine interfaces are demanding increasingly real-time,intuitive,and convenient modes of information feedback.As an emerging platform for human-machine interaction,alternating current electrolumi‑nescence-based visual sensors can directly convert external stimuli into optical signals,thereby advancing the de‑velopment of human-machine interaction.However,existing visual sensors generally rely on external alternating current excitation and still suffer from limited flexibility,insufficient system integration,and an inadequate abili‑ty to convert weak stimuli into clearly discernible visual signals.To address these issues,this paper presents a humidity-sensitive visual film sensor based on field-induced luminescence.The sensor adopts a multilayer flexi‑ble architecture consisting of a skin-adhesive layer,a conductive layer,a luminescent layer,and a sensing layer.Within the relative humidity(RH)range of 40%-95%,the sensor exhibits a pronounced high-contrast optical re‑sponse at an ionic liquid([EMIM][TFSI])mass fraction of 2%.Owing to its excellent conformability,flexibili‑ty,and stretchability,it can be stably laminated onto the human body and readily accommodate complex deformations.By integrating alternating-current electroluminescence with a humidity-responsive gel,we established a humidity-induced luminescence mechanism that enables direct visual readout of humidity variations.Meanwhile,through an energy-transfer pathway established between the human body and the ambient electromagnetic field,the film can be wirelessly driven without the need for a conventional rigid power supply,thereby improving both portabili‑ty and operational versatility.Furthermore,by exploiting the natural humidity of human skin,the film enables contactless visual interaction,offering a new design strategy for flexible,wireless,and perceptive human-ma‑chine interfaces,and demonstrating its potential for applications in smart interactive displays and wearable elec‑tronics.关键词
