From: Cross-Talk Immunity of PEDOT:PSS Pressure Sensing Arrays with Gold Nanoparticle Incorporation
(a) Schematic diagram of the Au-NP incorporated PEDOT:PSS pressure sensing 2 × 2 arrays and (b) the cross-sectional structures in A-A’ and B-B’ direction. (c) The measurement setup of the pressure sensing arrays. (d) The top view of a 2 × 2 CPE pressure sensing array structure with an active cell (00), adjacent cells (01, 10) and diagonal cell (11). The electrode width (w) is 0.3 cm, the spacing between two electrodes (s) is 0.7 cm and the tip size (d) is in the range of 1 to 2 cm. (e) The cross-talk effects of the PEDOT:PSS pressure sensing 2 × 2 arrays with different sizes of Au-NP incorporation. The tip size used in this study is 1.6 cm. The pressure is applied at active (00) cell and the resistance values are measured at adjacent (10) and diagonal (11) cells. The cross-talk values (CT) are calculated and shown in (f). The tip size dependence on cross-talk effects of the PEDOT:PSS pressure sensing 2 × 2 arrays without and with Au-NP incorporation of 20 nm in diameter for (g) the adjacent (10) and (h) diagonal (11) cells. The tip sizes used in this study are in the range of 1 to 2 cm.
