An ultra-thin, non-invasive wearable patch can be affixed to the arm or chest to monitor biomarkers released by cells into the bloodstream and eventually onto the skin. As these biomarkers reach an array of sensors embedded in the patch, they are adsorbed, triggering each sensor to emit a distinct signal. These signals are then analyzed and classified by AI and related software, with results transmitted wirelessly via RFID technology. Within just five minutes, healthcare professionals can access these results. The affordability of this skin-based patch makes it ideal for community-wide testing or remote monitoring of individuals at home, with data seamlessly transferred from the patch to a smartphone and then to the healthcare provider.
