Abstract

This paper presents a highly sensitive and multifunctional pressure sensor for precise gait pattern analysis. The sensor, fabricated using eutectic gallium indium (EGaIn) liquid metal and EcoFlex 00-30 silicone, features a microchannel architecture creating two independent sensing devices. Its high stretchability and flexibility result in a sensitivity of 66.07 MPa⁻¹ and a low measurement resolution of 0.056 kPa. The sensor accurately detects pressure distribution and effectively monitors human walking gait at various speeds, differentiating between walking postures. This device shows strong potential for clinical and rehabilitation applications in gait analysis.
