摘要： The apparatus includes a first gain adjuster, a second gain adjuster, an amplifier, a demodulator, a controller, and a change measuring unit. The first gain adjuster adjusts the gain of an input signal and outputs the gain-adjusted input signal as a first modulating signal, while the second gain adjuster adjusts the gain of an inverted input signal and outputs the gain-adjusted inverted input signal as a second modulating signal. The amplifier amplifies a modulated signal output from a junction between the first and second capacitors and outputs the amplified results. The demodulator demodulates the amplified results received from the amplifier in response to a control signal and outputs the demodulated result. The controller generates the control signal per unit period of the input signal and outputs the generated control signal to the demodulator. The change measuring unit measures the change in capacitance from the demodulated results received from the demodulator. An offset produced by parasitic capacitance is compensated without affecting the change in capacitance to be measured.

摘要： A rotary microactuator having optimally curved electrodes is provided. The rotary microactuator is optimally designed so that the interval between two electrodes, which are a rotor and a stator, is constant regardless of a distance from the central axis of the rotor. Thus, a parallel-plate configuration can generate a maximum driving force, and also can widen a driving range. In particular, in a rotary microactuator using parallel-plate configuration electrodes, the electrodes are optimally designed so that the interval between the electrodes remains constant regardless the radius by tilting the electrodes or by zigzagging the electrodes. Therefore, a driving force per a given area can be maximized.
