Ionic liquids and ion gels have useful properties such as conductivity, non-volatility and thermal stability. The purpose of this research is development of touch sensor composed only of soft material. Silicone rubber layers with micro-channel patterns, were fabricated against 3D printed molds. These silicone rubber layers were bonded to create enclosed micro-channels, and a conductive ion gel is injected into the micro-channels. Changes in electrical resistance of the ion gel under strain (that is on being pressed, bent, twisted and stretched) were measured. Results indicate predictable behavior of the developed sensor.
