Title:
SYSTEM AND METHOD FOR FALSE-COLOR SENSING AND DISPLAY
Document Type and Number:
WIPO Patent Application WO/2012/005907
Kind Code:
A3
Abstract:
A system and method for determining humidity based on determination of an offset voltage shift are disclosed. In one embodiment, a system for determining humidity comprises an electromechanical device comprising a first layer, a second layer, and a dielectric between the two layers, wherein the dielectric is spaced apart from at least one of the first and second layers in an unactuated state of the electromechanical device, and wherein the dielectric contacts both the first and second layers in an actuated state of the electromechanical device, a voltage source configured to apply, between the first and second layers, one or more voltages, and a processor configured to control the voltage source, to determine an offset voltage shift based on the applied voltages, and to determine information regarding humidity about the device based on the offset voltage shift.
