Carbon nanotubes have great potential in electronic and sensory applications due to their excellent electrical and mechanical properties. They have been used in various fields of research to reinforce matrix materials to enhance their mechanical, thermal, and electrical properties. On the other hand, a significant interest in the printed electronics had become evident in the past few years where additive manufacturing is utilized for the extrusion of the sensing material. In this study, we developed a fully printed flexible piezoresistive tactile sensor using multi-walled carbon nanotubes (MWCNT) as fillers for a polymeric matrix (PDMS). The sensing part is a 3-dimensional disc printed with direct ink process on top of a silver ink electrode which was also extruded using the same process. Compared to our previously reported design, this design allowed the decrease of the initial electrical resistance of the sensor without modifying the preparation process of the MWCNT-PDMS composite.
