Fig. 1From: Ultrafine and crosstalk-free 2D tactile sensor by using active-matrix thin-film transistor arraySchematic diagram of the PM array circuit with horizontal (1–3) and vertical (A–C) electrodes. The intersection points are pixels. The PSR sheets are indicated as variable resistors at each pixel. The gray dashed lines depict a crosstalk occurrence with the leakage and bypass currents. The dotted lines show another crosstalk occurrence with only the bypass currentBack to article page
