Title:
VARIABLE CAPACITANCE WITH DIELECTRIC FLUID
Document Type and Number:
WIPO Patent Application WO2006054006
Kind Code:
A3
Abstract:
The invention concerns variable capacitance (1) based on a novel principle: a dielectric fluid (20) is placed in the air gap formed by two capacitor electrodes (12, 14), the fluid being mobile towards and out of the cavity (10) formed between said two electrodes (12, 14). Advantageously, the dielectric fluid (20) is moved in accordance with the principle of communicating vessels, a second cavity (30) being in fluid communication with the first cavity. Actuating electrodes (46, 48) in the second cavity (30) cause a membrane (44) to be deflected so as to modify the relative levels of liquid in both cavities (10, 30).
