This paper presents the design, fabrication technique and characterization of tactile sensor which work based on piezoresistive. There are several journal papers that proposed various kind of tactile sensor design, however tactile sensing technology still have the potential to be improved. Since, there is less amount of study on the dependent of reduced graphene oxide concentration to performance. Therefore, this research is to fabricate tactile sensor which based on different concentration of reduced graphene oxide and polydimethylsiloxane. The concentration of graphene oxide is varying from 1mg/ml to 0.4mg/ml. Firstly, the related works on tactile sensor is collected and a design is proposed. The fabricated tactile sensor has two layers of polydimethylsiloxane, in which reduced graphene oxide will on one layer and the electrode will be on another layer. Different force applied on polydimethylsiloxane, will cause different contact area between reduced graphene oxide and electrode, as a result, the resistance change and force are being translated into resistance value.References
