The addition sensing device of sweat to wearable biostress sensors would eliminate the need for using multiple gadgets for healthcare analysis. Due to the distinct package fashion of sensor interface for biostress and biomolecule, achieving permeability and multifunctionality in an integrated wearable sensor remains a formidable challenge. Here, a viscose fabrics (VCFs)@silver (Ag) sensing material and encapsulating strategy by multi-microporous membranes (M-MPM) are developed, and simultaneous detection for muscle strain and molecule biomarkers in sweat (glucose, lactate, uric acid) is realized. The package interface exhibits good breathability, directional, and fast sweat transport without interception due to its wetting gradient enabled by the 3D-stacking for VCFs@Ag and M-MPM, which subjoins sensing function of sweat on the biostress sensing platform. And, the filtration effect of M-MPM can resist the pollutant interference to the hand-held surface-enhanced Raman scattering spectrum on skin surface. Then, a bidirectional memory network is constructed to correct for the changes in electrical conductivity of VCFs@Ag under the influence of sweat infiltration. With the help of a machine learning pipeline, the accuracy of multimodal recognition increased to 88.6%. As proof of concept, the package interface of M-MPM/VCFs@Ag provides the feasibility of simultaneous monitoring of the muscle strain and sweat with a single sensor.
在可穿戴生物应激传感器中添加汗液传感装置将不再需要使用多个小工具进行医疗保健分析。由于生物应激和生物分子的传感器接口包装方式不同,在集成可穿戴传感器中实现渗透性和多功能性仍然是一项艰巨的挑战。在此,开发了一种粘胶织物(VCFs)@银(Ag)传感材料和通过多微孔膜(M-MPM)的封装策略,并实现了对汗液中肌肉应变和分子生物标志物(葡萄糖、乳酸、尿酸)的同时检测。该封装接口具有良好的透气性、定向性和快速汗液传输能力,由于其通过VCFs@Ag和M-MPM的3D堆叠实现的润湿梯度,汗液传输不会受到拦截,这为生物应激传感平台增添了汗液传感功能。而且,M-MPM的过滤效果可以抵抗污染物对皮肤表面手持式表面增强拉曼散射光谱的干扰。然后,构建了一个双向记忆网络来校正汗液渗透影响下VCFs@Ag的电导率变化。借助机器学习管道,多模态识别的准确率提高到了88.6%。作为概念验证,M-MPM/VCFs@Ag的封装接口提供了使用单个传感器同时监测肌肉应变和汗液的可行性。
