a Fabrication of stretchable silver ink-based resonators and translation to skin. b Transmission profile of the MI array measured under various encapsulation thicknesses (insulating top and bottom of the skin patch) and background medium loss. c Resonance properties of the silver ink-based coil under normal strain in a dry background environment on a 0.5 mm thick PDMS substrate. d Sensitivity and repeatability of the resonant coil under normal strain. e Demonstration of mechanical stretchability of a fully encapsulated resonator under excessive applied strain. f Reliability test of flexibility under up to 10,000 full bending cycles. g, h The coil exhibits no major difference between the resonance frequency profile of the first and last bending cycles.
