    • Under one aspect, a resonator 400 includes a nanotube element 410 including a non-woven fabric of unaligned nanotubes and having a thickness, and a support structure 404 defining a gap 406 over which the nanotube element 410 is suspended, the thickness of the nanotube element 410 and the length of the gap 406 being selected to provide a pre-specified resonance frequency for the resonator 400 The resonator 400 also includes a conductive element 412 in electrical contact with the nanotube element 410, a drive electrode 408 in spaced relation to the nanotube element 410, and power logic in electrical contact with die at least one drive electrode 408 The power logic provides a series of electrical pulses at a frequency selected to be about the same as the pre-specified resonance frequency of the resonator 400 to the drive electrode 408 during operation of the resonator 400, such that the nanotube element 410 responds to the series of electrical pulses applied to the drive electrode 408 by making a series of mechanical motions at the resonance frequency of the resonator 400.
    • 在一个方面,谐振器400包括纳米管元件410,纳米管元件410包括非对准纳米管的非织造织物并具有厚度,以及支撑结构404,其限定了纳米管元件410悬挂在其上的间隙406,纳米管元件的厚度 410,并且间隙406的长度被选择为谐振器400提供预定的谐振频率。谐振器400还包括与纳米管元件410电接触的导电元件412,与纳米管相隔离的驱动电极408 元件410以及与裸片至少一个驱动电极408电接触的功率逻辑功率逻辑提供一系列电脉冲,频率选择为与谐振器400的预先指定的谐振频率相对于驱动电极 在谐振器400的操作期间,使得纳米管元件410响应于施加到驱动电极408的一系列电脉冲 在共振器400的共振频率下进行一系列机械运动。
