Tactile sensors are devices or systems which measure physical signals such as resistance, capacitance, voltage, and frequency through physical contact. Recently, the most studied tactile sensors are silicon based tactile
sensors and polymer based tactile sensors.
Silicon-based tactile sensors are not flexible, and the fabrication cost of sensors is expensive due to the insertion of strain gages or copper electrodes. Meanwhile, a polymer-based tactile sensor having a planar shape has flexibility and stretchability and can be attached to a curved surface. However, when a planar tactile sensor is attached to a curved surface, there is a limitation that the initial mechanical properties are changed due to deformation of the sensor. Therefore, it is suitable to use a tactile sensor having a suitable curvature.
The goal of this study is to develop the non - planar tactile sensor that can be used on a curved surface. When a non-planar tactile sensor is manufactured using a mold, different core is required for each shape of the curved surface to be attached. The study proposes the manufacturing process of the tactile sensor with arbitrary curvature using the variable core mold. The variable core mold means that the shape of the core ischanged by the push bar. The core produces different curvatures depending on the position of the push bar. Thickness of the sensor was apprehended by the inclination angle of the core. Therefore, thickness of the sensor material was measured depending on the angle of inclination. The tactile sensor was fabricated using a variable core mold, and the voltage of the sensor which changes by external force was measured by a voltage measuring device.
