Title:
VARIABLE CAPACITANCE ELEMENT AND MANUFACTURING METHOD, AND CAPACITANCE SETTING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2010/055545
Kind Code:
A1
Abstract:
Disclosed are a highly reliable variable-capacitance element that can operate with low power consumption, and a manufacturing method therefor. Additionally provided is a capacitance setting method for the variable-capacitance element. The variable-capacitance element comprises two opposing substrates (11) and (12), electrodes (2), (3), (4), (5) and (6) formed on the opposing surfaces of each of the substrates, dielectric layer (15) provided on the surface of one of the two opposing electrodes, and organic actuators (11) and (12) formed as layers between the two opposing substrates, wherein drive power is supplied to the organic actuators. The electrostatic capacitance can be set to any value by using the “latch function” or “latch state” of the organic actuators.
