Wireless, Battery‐Free Epidermal Electronics for Continuous, Quantitative, Multimodal Thermal Characterization of Skin

Abstract: Precise, quantitative measurements of the thermal properties of human skin can yield insights into thermoregulatory function, hydration, blood perfusion, wound healing and other parameters of clinical interest. The need for wired power supply systems and data communication hardware limit, however, practical applicability of existing devices designed for measurements of this type. Here, we report a set of advanced materials, mechanics designs, integration schemes and wireless circuits as the basis for wireless,… Show more

“…Current solutions for wireless sensor interconnection either require each sensor to be independently powered (such as with batteries) 11,[17][18][19][20][21][22][23] or have a very limited range of operation (few centimetres) [32][33][34][35][36][37][38][39] . Networks of skin-mountable sensors use.…”

“…Near-field communication (NFC) is an alternative wireless technology in which sensors are inductively powered by a wireless reader 25,31 . Because NFC-based sensors can be battery-free, low-cost, and secure against eavesdropping, this technology has emerged as a versatile platform for developing skin-mounted or implanted electronics capable of measuring heart rate, tissue oxygenation, sweat electrolyte composition, ultraviolet light exposure, and other physiological parameters [32][33][34][35][36][37][38][39] . A major limitation of NFC technology, however, is that the sensors can function only within the near-field of the reader, which is at most a few centimetres for a mobile reader such as a smartphone 25,31 .…”

“…Soft, flexible, wireless sensors for continuous flow monitoring The basic principles of the measurement can be found elsewhere [36][37][38][39] . In the devices reported here, a miniaturized (<5 mm diameter) thermal actuator delivers small, precisely controlled thermal power (<5 mW/mm 2 ) to the surface of the skin, thereby creating an imperceptible local increase in temperature (~5 K).…”
