A Study on Resistivity Behaviour of Conductive Rubber Sheet (CRS) and Quantum Tunnelling Composites (QTC) Pills for Tactile Sensor Application

Abstract

This paper presents the work of investigating and comparing the uses of CRS and QTC Pills as a tactile sensor material for Robotic Hand application. The materials were tested for their resistivity characteristics to determine the data reproducibility of the materials. The experiments were conducted based on three parameters; the supply voltage, the separation gap, and the sensor construction against the force/ load that had been exerted onto the materials. The results showed that CRS could cover the lower loading range when compared to QTC Pills. However, the data reproducibility of QTC Pills was better compared to those of CRS, thus making it more suitable to be used as a material for tactile sensing application. Therefore, this paper highlights the potential of these two materials as a tactile sensing transducer, and later, can be used as a useful guideline when designing a tactile sensor with these materials.
