Bio‐Integrated Epidermal Wireless Sensors for Human Health Monitoring and Sensation Recovery

Originally introduced by the material science community, skin-mounted electronics is nowadays the new frontier for unobtrusive body-centric monitoring systems. Current advances of the Radiofrequency Identification (RFID) technology can boost this emerging class of bio- integrated skin devices exploiting low-power (even passive) wireless communication and sensing interfaces. This contribution resumes the performance of UHF RFID epidermal antennas, their optimal size and the upper bounds in the achievable radiation gain. Finally, three promising applications are introduced. Two of them are devoted to the remote and unobtrusive monitoring of human health, the third one aims at helping impaired people in restoring and enhancing their sensory capabilities.
