A strategy for assessing blood microcirculation and tissue hydration relies on monitoring the temperature and thermal conductivity of skin, respectively. It is now shown that arrays of micrometre-sized sensors and heaters can be integrated on stretchable substrates that conformably adhere to the skin; these devices allow spatially resolved heating and real-time temperature mapping in patients without limiting their motion.
