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.
