Soft and stretchable electronics have garnered significant attention in various fields,such as wearable electronics,electronic skins,and soft robotics.However,current wearable electronics made from mate-rials like conductive elastomers,hydrogels,and liquid metals face limitations,including low permeabil-ity,poor adhesion,inadequate conductivity,and limited stretchability.These issues hinder their effectiveness in long-term healthcare monitoring and exercise monitoring.To address these challenges,we introduce a novel design of web-droplet-like electronics featuring a semi-liquid metal coating for wearable applications.This innovative design offers high permeability,excellent stretchability,strong adhesion,and good conductivity for the electronic skin.The unique structure,inspired by the architecture of a spider web,significantly enhances air permeability compared to commercial breathable patches.Furthermore,the distribution of polyborosiloxane mimics the adhesive properties of spider web mucus,while the use of semi-liquid metals in this design results in remarkable conductivity(9 x 106 S/m)and tensile performance(up to 850％strain).This advanced electronic skin technology enables long-term monitoring of various physiological parameters and supports machine learning recognition functions with unparalleled advantages.This web-droplet structure design strategy holds great promise for com-mercial applications in medical health monitoring and disease diagnosis.
