Matrix Addressable Arrays of Microelectrochemical Devices
Abstract
Funding from the AFOSR (F49620-94-1-0449) made possible: (a) to establish that the vectorial and non-linear nature of the redox process provides a switching mechanism that can be used to build matrix-addressable electrochromic displays without cross-talk and with no need for fabrication of non-linear elements -like transistor switches- within each pixel. In contrast, it should be noted that in order to eliminate cross-talk in liquid crystal displays (LCDs) one transistor switch must be incorporated within every picture element (pixel), resulting in high cost; (b) to develop sol-gel materials with electrochromic properties for light modulation applications, or photoluminescent properties for chemical sensor applications; and, (c) to investigate and establish that strong, reproducible and quantifiable stirring effects with no moving parts can result when transverse magnetic fields are applied across the current flowing through electrochemical cells. The parameters controlling the magnetohydrodynamic stirring effect have been identified, isolated and studied independently, resulting in an equation that comprises the magnetic field equivalent of the well-known Levich equation for the rotating electrode.
