Organic electronic and polymer memory devices offer the potential for cheap, simple memories that could compete across the whole spectrum of digital memories, from low cost, low performance applications, up to universal memories capable of replacing all current market leading technologies, such as random access memories, hard disk drives and Flash memories. Organic memory devices (OMDs) are simple, two terminal metal-insulator-metal (MIM) bi-stable devices that can exist in two distinct conductivity states. Each state is induced by applying different voltages across the device terminals. Here we review the developing methods for the integration and interfacing of molecular components that have been found for the performing information functions (memory, processing) on a molecular scale.

The color sensing ability of a data acquisition prototype system integrating a 32 linear array of 1D amorphous silicon position sensitive detectors (PSD) was analyzed. Besides being used to reproduce a 3D profile of highly reflective surfaces, here we show that it can also differentiate primary red, green, blue (RGB) and derived colors. This was realized by using an incident beam with a RGB color combination and adequate integration times taking into account that a color surface mostly reflects its corresponding color. A mean colorimetric error of 25.7 was obtained. Overall, we show that color detection is possible via the use of this sensor array system, composed by a simpler amorphous silicon pin junction. © 2013 Elsevier B.V. All rights reserved.
