Multiscale porous elastomer substrates for multifunctional on-skin electronics with passive-cooling capabilities
Abstract
Point-of-care thermal management (e.g., joule heating, passive cooling) shows promising applications in body temperature regulations, which can improve human comfort and reduce energy consumption. On-skin electronics with joule-heating elements have been reported. However, the research of making on-skin electronics with passive-cooling functionalities is still rare. By using multiscale porous polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene as supporting substrates, we have developed multifunctional on-skin electronics with outstanding passive-cooling capabilities, delivering around 6 °C cooling effects under a solar intensity of 840 W⋅m−2. Other desired properties, rooted in porous SEBS substrates, include high breathability and outstanding waterproofing. In addition, a variety of bioelectronic devices are made on porous SEBS substrates via spray printing of silver nanowires (Ag NWs). The enabled devices demonstrate high performance and are recyclable.
