Demonstration of wearable devices with the flexible pressure sensor based on the PDMS/MS composite. For a wearable application, the sensor is placed onto the index finger and sole of the shoe. (a) The angle of the index finger is relaxed and bent at various bending stages. (b) Measurement results of relative capacitance values according to index finger’s angle. (c) Photos of the shoe and shoe insole with an attached sensor. (d) Capacitance response of the pressure sensor with repeated motions such as walking and running.
