Paper Abstract

Development of tactile sensing technology has promoted intelligent human-machine interaction and recently has evolved out as one of the most promising area of electronics. Tactile sensing is a milestone in this field as it can extend the detection mode of tactile sensor through air. In this paper, we fabricated a tactile sensor using cellulose nanocrystal modified with graphene by isocyanate grafting. The new material is transparent, ecofriendly and integrated the capability of tactile sensing with fast response, high stability and high reversibility. Various materials from conducting metals to a human hand were checked for tactile sensing capability. It is found that the fabricated sensor could detect a human hand at a distance up to 6 mm away from the sensor. Combining the results, the discrete, flexible dual-mode tactile sensor fulfilled the technical and operational objectives of this work .
