Abstract :
In this paper, we propose and demonstrate a transparent and flexible tactile sensor which is designed for multi touch screen application. The sensor module is composed of 2-D array capacitive tactile cells to measure the touch force on multiple positions. The device was fabricated with transparent materials on transparent plastic substrate. The touch input was measured by the capacitance variation resulting from the mechanical deformation of parallel plate capacitor.
