Conventional wearable sensors often suffer from mechanical damage, unstable skin adhesion, and limited durability of biochemical sensing, which undermine long\u2010term reliability. Here, we report a fully self\u2010healing wearable biosensing system that integrates a laser\u2010induced graphene (LIG) strain sensor, a molecularly imprinted polymer (MIP) cortisol sensor, microfluidic channels with cross\u2010hatch patterned fillers, a catechol\u2010functionalized polyurethane (CF\u2010PU) adhesive, and an oxime\u2010carbamate bond\u2010based polyurethane (OC\u2010PU) encapsulation layer for simultaneous monitoring of pulse signals and sweat cortisol levels. The LIG\u2010based strain sensor provides pulse waveforms, while the MIP\u2010based cortisol sensor enables selective detection of cortisol in human sweat, achieving a detection limit of 10 pM. The microfluidic channels ensure continuous sweat collection and delivery to the sensing interface, and the CF\u2010PU adhesive maintains skin attachment in the presence of sweat. This system maintains reliable biosignal acquisition under repeated cycles of mechanical damage and self\u2010healing at 65\u00b0C for 6\u00a0h, as well as prolonged operation. As a result, the system enables non\u2010invasive monitoring of physiological and biochemical stress markers after mechanical damage and offers a fully self\u2010healing stress\u2010monitoring platform for next\u2010generation health applications.<\/jats:p>","DOI":"10.1002\/smll.75079","type":"journal-article","created":{"date-parts":[[2026,8,5]],"date-time":"2026-08-05T09:24:42Z","timestamp":1785921882000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Fully
