Abstract
S/m has the advantages of light weight, high flexibility, and superb mechanical stability. As a result, a small-size (50 mm × 50 mm) and flexible GAF-based antenna operating at 3.13-4.42 GHz is achieved, and this GAF antenna-based wireless wearable sensor shows high strain sensitivities of 34.9 for tensile bending and 35.6 for compressive bending. Furthermore, this sensor exhibits good mechanical flexibility and structural stability after a 100-cycle bending test when attached to the back of the hand and the wrist, which demonstrates broad application prospects in health-monitoring devices, electronic skins, and smart robotics.
