we demonstrate a tandem interactive sensing display enabling not only direct visualization of both pressure and temperature but also quantitative de-convolution of these two simultaneously varied stimuli. Our tandem display consists of 5 polymer layers vertically stacked on a transparent substrate. Impedance change of two responsive layers upon dynamic temperature and pressure is instantly detected, at the same time giving rise to stimuli-interactive electroluminescence of light emitting unit and, respectively when AC field is applied between two parallel polymer electrodes. Dynamic and simultaneous variation of temperature from 30 to 80 C and pressure from X to 20kPa is conveniently mapped in 3 dimensional coordinate of light intensity (z-axis) and color coordinate (x-y plane), resulting in a 2 dimensional contour surface plot. The plot allows for efficient and quantitative de-convolution of the unknown information of various mixed stimuli. |
