Figure 4

Mechanical and electromagnetic properties of the stretchable liquid-metal antenna. (a) Optical images of the device under uniaxial strain up to 30%. Scale bar, 4 mm. (b) FEA results for the stress distributions associated with devices under uniaxial stretching up to 30%. (c) Change in the resistance of the NFC inductive coil under uniaxial strain. (d) Phase response under uniaxial strain. (e) Change in the resonance frequency and Q factor under uniaxial strain. Experimentally measured and theoretically calculated data are shown with solid and dotted lines, respectively. FEA, finite element analysis.
