In this research, we introduce a strain-insensitive soft pressure sensor using 3D-printed microchannel mold and liquid metal for health monitoring applications. Our soft pressure sensor consists of elastomer and liquid metal for its intrinsic stretchable property. Also, serpentine geometric pattern of the microchannel enabled the sensor to be strain-insensitive for stable signal response and recovery in wearable applications. Various experiments for sensor characterizations were conducted and the study of FEM simulation verified the strain-insensitive behavior of serpentine pattern. As a health monitoring application, body pressure distribution was monitored using several pressure sensors attached on the clothes and the body pressures were compared according to various lying conditions.
