    • An apparatus for converting mechanical vibrational energy into electrical power includes first and second collecting electrodes configured for connection to terminals of an electrical load, and an electret placed facing the first electrode. The electret is mounted so as to move relative to the first electrode in one degree-of-freedom in a plane. Relative movement between the electret and the first electrode induces a potential difference across the electrodes. The electret has a continuous layer and a series of protrusions, each of which extends perpendicular to the plane. These protrusions are distributed in the degree-of-freedom with a first pitch, which is smaller than the travel between the first electrode and the electret. The first electrode has faces facing the electret. These faces are distributed in the degree-of-freedom with a second pitch identical to the first pitch.
    • 用于将机械振动能转换为电力的装置包括构造成用于连接到电负载的端子的第一和第二集电电极以及面向第一电极放置的驻极体。 驻极体被安装成相对于第一电极在平面内的一个自由度上移动。 驻极体和第一电极之间的相对运动在电极两端产生电位差。 驻极体具有连续层和一系列突起,每个突起垂直于平面延伸。 这些突起以比第一电极和驻极体之间的行进小的第一间距以自由度分布。 第一电极具有面向驻极体的面。 这些面以与第一间距相同的第二间距以自由度分布。

    • An apparatus for amplifying a vibratory movement includes a micromechanical device having an interface for fixedly joining it to a vibrating member; a mass mounted to be mobile in at least one degree of freedom relative to the interface; a spring capable of exerting a return force between the mobile mass and the interface; an orientation-detecting member for detecting the orientation of the shift of the interface according to said degree of freedom; and a coupling member for coupling the mobile mass to the interface. The coupling member is configured to couple the mobile mass to the interface when an orientation of shift of the interface is opposite that of the mobile mass and to uncouple the mobile mass from the interface before a change in orientation of the interface and when the orientation of shift of the interface is identical to that of the mobile mass.
    • 用于放大振动的装置包括具有用于将其固定地连接到振动构件的界面的微机械装置; 安装成相对于界面至少一个自由度移动的质量; 能够在移动体和界面之间施加返回力的弹簧; 取向检测构件,用于根据所述自由度检测界面的移动方位; 以及用于将移动质量块连接到界面的联接构件。 联接构件被配置为当接口的移动方向与移动质量块的移动方向相反时,将移动质量块耦合到接口,并且在接口的取向改变之前,以及当界面的取向改变时,将移动质量与界面分离 接口的移位与移动块的移位相同。
