This paper presents the work of investigating the used of Quantum Tunneling Composites (QTC) Pills as a tactile sensor material. The QTC Pills was tested for their resistivity characteristics to determine the sensor sensitivity, time of response and its allowable working range. The experiments were conducted base on the two parameters; the voltage, and the separation gap against the force/ load that exerted onto the QTC Pills. The results show that with a 5 V supply voltage and 0.5 mm separation gap of a side-by-side sensor construction, the usage of the QTC Pills as a tactile sensor can be optimized. Besides that the resistivity values established from the repeated experiment using QTC Pills produce the similar value and result. This makes the material suitable to be used as a tactile sensor material for the robotic hand.
