Tactile sensors based on organic field-effect transistors

Electronic skin has been widely considered promising for electronic applications in the next-generation robots, wearable electronics, and prosthetics. In recent years, great progress has been made in the field of piezo-resistive and capacitive pressure sensors. However, to realize the low-power consumption high-resolution electronic skin, it is critical to integrate these sensors with organic field-effect transistors (OFETs) for active-matrix sensory arrays. Compared to conventional silicon-based devices, OFETs possess mechanical flexibility and potentially provide low-cost large-area fabrications. Therefore, the integration of OFETs and pressure sensors will provide an ideal solution to achieve the commercialization of electronic skin. This feasibility has been introduced in this chapter.
