Abstract
In this work, we present a novel piezoresistive tactile sensing array which is capable of retaining and erasing tactile images. The sensing element comprises polydimethylsiloxane (PDMS) polymer mixed with multi-wall carbon nanotubes (MWCNTs) and silver nano-particles by using the dielectrophoresis (DEP) technique. When the sensing element is pressed, the resistivity increases and retains. The resistivity can be recovered (“flashed”) to the original value by DEP again. The performance and repeatability of the proposed novel sensing elements is presented. Also, the measured results are demonstrated.
