Conventional health monitoring often relies on biofluids such as blood, urine, or sweat, which require invasive or cumbersome collection processes and stringent storage protocols—contributing to high healthcare costs. To overcome these limitations, iHealthtech Principal Investigator Dr Liu Yuxin and Dr Yang Le, Principal Scientist and Head of the Sensors and Flexible Electronics Department at A*STAR’s Institute of Materials Research and Engineering (IMRE), have co-developed a skin-interfacing wearable biosensor. This soft, adhesive device captures and analyzes solid-phase biomarkers—minute molecular residues excreted through the skin’s surface—offering a non-invasive, real-time alternative to traditional fluid sampling. The technology has demonstrated success in monitoring lactate levels in athletes and holds promise for early detection of diseases such as cardiovascular disorders and stroke, paving the way for more accessible and continuous health monitoring. The work was published in the journal Nature Materials on 12 June 2024.
