可变电容元件、可变电容设备和驱动可变电容元件的方法
摘要：
本发明涉及可变电容元件、可变电容设备和驱动可变电容元件的方法。可变电容元件包括第一固定电极和第二固定电极，其相互绝缘；可动电极，其设置成面对所述第一固定电极和所述第二固定电极；电介质层，其设置在所述可动电极与所述第一固定电极以及所述第二固定电极之间；第一接线部分，其用于根据所述可动电极的电位将第一驱动电压施加到所述第一固定电极；和第二接线部分，其用于根据所述可动电极的电位将第二驱动电压施加到所述第二固定电极，所述第二驱动电压具有与所述第一驱动电压的极性不同的极性。
摘要（英）：

The invention relates to a variable capacitive element, a variable capacitive device, and a method for driving the variable capacitive element. The variable capacitive element includes a first fixed electrode and a second fixed electrode that are insulated from each other, a movable electrode arranged to face the first fixed electrode and the second fixed electrode, a dielectric layer provided between the movable electrode and the first fixed electrode as well as the second fixed electrode, a first wiring part for applying a first driving voltage to the first fixed electrode with reference to a potential of the movable electrode, and a second wiring part for applying a second driving voltage to the second fixed electrode with reference to the potential of the movable electrode, the second driving voltage having a polarity different from a polarity of the first driving voltage.
