文摘Skin-integrated wearable electronics enable continuous,medical-grade monitoring and therapy in daily life,but must balance conflicting needs related to mechanics,power,and communication.This review uses a dual-interface approach that separates the sensor-receiver interface,which handles wireless data and energy transfer,from the sensor-skin interface,where physiological signals are converted and mechanical and biological integration occur.We first reviewed wireless connections designed for skin electronics,focusing on Bluetooth Low Energy(BLE),Radio Frequency Identification(RFID)/Near-Field Communication(NFC)systems,and hybrid systems.Next,we examine sensor-skin interfaces ranging from mediated contact layers such as hydrogels for wearable ultrasound and soft conductive electrodes,to skin-conformal direct-contact methods based on structural mechanics,and ultrathin epidermal devices.Finally,we discuss cross-interface coupling,emphasizing how antenna layouts,power budgets,and body-induced RF effects limit mechanical design,and how skin mechanics influence link reliability.We conclude by exploring opportunities in battery-free and energy-autonomous systems,body-coupled communication,and integration with artificial intelligence(AI)-enabled digital health,positioning future electronic skins as soft,networked platforms that are comfortable and reliable.

文摘Wearable electronics incorporating proteins for biocompatibility have garnered significant research attention,given their potential applications in biocompatible medical devices,artificial skin,humanoid robots,and other fields.However,a notable challenge exists,as many wearable electronics currently lack those essential properties due to issues such as non-biological compatibility,as well as insufficient mechanical and conductive performance.Here,we have developed a hybrid keratin(KE)hydrogel by incorporating a liquid metal(LM,eutectic gallium-indium alloy)to design a wearable electronic device with excellent biocompatibility,enhanced conductivity,and good mechanical properties.The resulting keratin liquid metal(KELM)hydrogel demonstrates favorable mechanical characteristics,including good tensile strength(166 kPa),impressive stretchability(2600%),and long-term stability.Furthermore,it exhibits good conductivity(6.84 S·m^(-1))and sensitivity as a sensing material(gauge factor(GF)=7.03),rendering it suitable for constructing high-performance strain sensors.Notably,the KELM hydrogel-based wearable electronics extend their functionality to monitoring marine inhabitants'health.This innovative application provides new insights for designing the next generation of biomimetic electronic devices,with potential applications in human-machine interfaces,electronic skin,artificial intelligence,and health monitoring.

文摘Due to its ability to convert body heat into electricity,organic thermoelectric material is considered a promising and smart maintenance-free power source to charge wearable electronics.However,developing flexible n-type organic thermoelectric materials and wearable p/n junction thermoelectric devices remains challenging.In this work,two insulated polyamides(PA6 and PA66)that have been widely used as fiber materials are employed as novel dopants for converting p-type single-walled carbon nanotubes(SWCNTs)to n-type thermoelectric materials.Because of the electron transferability of the amide group,polyamide-doped SWCNTs exhibit excellent thermopower values as large as-56.0μV K^(-1) for PA66,and-54.5μV K^(-1) for PA6.Thermoelectric devices with five p/n junctions connected in series are fabricated.The testing device produces a thermoelectric voltage of 43.1 mV and generates 1.85μW thermoelectric power under temperature gradients of approximately 80 K.Furthermore,they display charming capability for temperature recognition and monitoring human activities as sensors.These promising results suggest that the flexible polyamide-doped SWCNT composites herein have high application potential as wearable thermoelectric electronics.

文摘High-density interconnect(HDI)soft electronics that can integrate multiple individual functions into one miniaturized monolithic system is promising for applications related to smart healthcare,soft robotics,and human-machine interactions.However,despite the recent advances,the development of three-dimensional(3D)soft electronics with both high resolution and high integration is still challenging because of the lack of efficient manufacturing methods to guarantee interlayer alignment of the high-density vias and reliable interlayer electrical conductivity.Here,an advanced 3D laser printing pathway,based on femtosecond laser direct writing(FLDW),is demonstrated for preparing liquid metal(LM)-based any layer HDI soft electronics.FLDW technology,with the characteristics of high spatial resolution and high precision,allows the maskless fabrication of high-resolution embedded LM microchannels and high-density vertical interconnect accesses for 3D integrated circuits.High-aspect-ratio blind/through LM microstructures are formed inside the elastomer due to the supermetalphobicity induced during laser ablation.The LM-based HDI circuit featuring high resolution(~1.5μm)and high integration(10-layer electrical interconnection)is achieved for customized soft electronics,including various customized multilayer passive electric components,soft multilayer circuit,and cross-scale multimode sensors.The 3D laser printing method provides a versatile approach for developing chip-level soft electronics.

文摘Textiles with electronic components offer a portable and personalized approach for health monitoring and therapy.However,there is a lack of reliable strategy to integrate layered circuits and high-density chips on or inside textiles,which hinders system-level functionality and untethered user experiences.Herein,we propose monolithically integrated textile hybrid electronics(THE)on a textile platform,with multimodal functions and reliable performances.The textile system encompasses flexible electrodes,laser-induced sensors,and surface-mount devices,along with double-layer circuits interconnecting all of them.Vertical conductive paths are rendered by liquid metal composites infiltrated into textiles,which allows resistances less than 0.1?while reserving intact textile structures.The assembled THE exhibits endurance to handwashing and crumpling,as well as bendability.We customize a wireless textile patch for synchronously tracking multiple physiological indicators during exercise.Furthermore,a textile band is elaborated for monitoring and alleviating muscular fatigue,demonstrating potential in closed-loop diagnosis and treatment.
