Design of a flexible force-sensing antenna for biomedical monitoring
We present a proximity-coupled meandered patch antenna implemented in a multilayer substrate for biomedical monitoring applications. The antenna's resonant frequency shifts to lower bands at a rate of 40.77 MHz/N when force is applied perpendicular to the radiating patch. Remote interrogation at a distance of 17 cm in an anechoic chamber demonstrated that the high-gain horn antenna detects this frequency shift when masses are applied to the radiating patch. These findings suggest that the proposed antenna sensor is suitable for force sensing in wearable healthcare.

Abstract
We present a proximity-coupled meandered patch antenna implemented in a multilayer substrate for biomedical monitoring applications. The antenna's resonant frequency shifts to lower bands at a rate of 40.77 MHz/N when force is applied perpendicular to the radiating patch. Remote interrogation at a distance of 17 cm in an anechoic chamber demonstrated that the high-gain horn antenna detects this frequency shift when masses are applied to the radiating patch. These findings suggest that the proposed antenna sensor is suitable for force sensing in wearable healthcare.
