Comparison of wireless, NFC devices during stretch with and without a strain-isolating substrate. a-b) Top view of an NFC device on phantom skin stretched to 50% a) with and b) without a liquid-filled cavity. The fiducial markers show the deformation at the interface between the phantom skin and the device. c-f) Corresponding computational results for the interface– shear stress c) with and d) without a liquid-filled cavity, normal stress e) with and f) without a liquid-filled cavity. g-h) Computed strain distribution on the NFC device g) with and h) without a liquid-filled cavity.
