摘      要：Epidermal electronic systems feature physical properties that approximate those of the skin,to enable intimate,long-lived skin interfaces for physiological measurements,human–machine interfaces and other applications that cannot be addressed by wearable hardware that is commercially available today.A primary challenge is power supply;the physical bulk,large mass and high mechanical modulus associated with conventional battery technologies can hinder efforts to achieve epidermal characteristics,and near-field power transfer schemes offer only a limited operating *** we introduce an epidermal,farfield radio frequency(RF)power harvester built using a modularized collection of ultrathin antennas,rectifiers and voltage *** components,separately fabricated and tested,can be integrated together via methods involving soft contact *** studies of the individual components and the overall performance in various dielectric environments highlight the key operational features of these systems and strategies for their *** results suggest robust capabilities for battery-free RF power,with relevance to many emerging epidermal technologies.
