Title:
MINIATURE ELECTRO-OPTIC DEVICE AND CORRESPONDING USES THEREOF
Document Type and Number:
WIPO Patent Application WO/2004/046807
Kind Code:
A1
Abstract:
The invention relates to a miniature electro-optic device comprising: a first zone which is disposed face-to-face with a second zone; a first capacitor plate; a second capacitor plate which is disposed in the second zone and which is smaller than or equal to the first plate; an intermediate space between said two zones; a conductive element which is disposed in the aforementioned intermediate space, which is independent of the lateral walls and which moves therethrough as a function of voltages present between the two plates; two light input/output points belonging to an optical circuit; and a stop element. According to the invention, when in contact with the above-mentioned stop element, the conductive element alters the light passage state between the input/output points. The inventive device can be used as an accelerometer, an inclinometer, a Coriolis force detector, a microphone, for acoustic applications, for the production of an optical switching matrix, for the projection of images, and as a pressure, flow, temperature, gas sensor, etc.
