In this work, a large-area tactile sensing array with high sensitivity is reported. The sensing elements of the array consist of multiwall carbon nanotubes dispersed in polydimethylsiloxane polymer. A novel fabrication process using a universal applicator is proposed for realizing large-area conducting polymer films. In addition, a nylon membrane filter is employed as a mold for creating microdome patterns, which are essential for increasing the sensitivity. The major advantages of the proposed device include ultrahigh sensitivity, flexibility, and a simple fabrication process. The sensing mechanism involves utilizing the contact resistance between the electrode and the conductive polymer film. A demonstration of the application of the tactile sensing array is presented.
