Abstract: The disclosure provides a magnetic field sensor for sensing the magnetic field caused by a current to be measured, which includes: substrate; a first drive electrode with a path for flowing a reference current supplied from the substrate arranged so as to be moveable by the magnetic field of the current to be measured; and a second drive electrode with a path for flowing a reference current supplied from the substrate arranged so as to be moveable by the magnetic field of the current to be measured, thus measuring the variation of a capacitance caused by the movement of the first drive electrode and the second drive electrode. Hence, the sensing is achieved by the two drive electrodes with no reference electrode, thus maximizing the mechanical displacement to improve the sensing capability.

Abstract: The disclosure provides a MEMS device including: a fixed substrate having a cavity; a driving unit disposed in the cavity and floating above the fixed substrate; and an elastic unit for physically connecting the fixed substrate with the driving unit and varying the height of the driving unit according to a control current, wherein the elastic unit includes a bimorph driving unit connected to the fixed substrate and bent according to the control current, a spring connected to the driving unit, and a frame connecting the bimorph driving unit to the spring. Therefore, in order to overcome the limitations according to the power consumption and the size-reduction due to a coil and a magnet, the MEMS device drives one lens and thus can reduce the power consumption and the size thereof.

Abstract: The present invention provides an amplitude modulator, which is disposed in an area through which a magnetic field flows so as to modulate amplitudes, comprising: a substrate; a first driving electrode which receives a first frequency signal and a second frequency signal supplied from the substrate and carries out resonant motion by the magnetic field; and a second driving electrode for receiving the second frequency signal and carries out resonant motion by the first driving electrode and the magnetic field, wherein a modulated signal is generated by modulating the amplitudes of the first and second frequency signals through the resonant motions of the first and second driving electrodes. Therefore, since the signal generated by modulating a carrier signal through mechanical resonance according to the magnetic field is outputted, amplitude modulation can be carried out without a complicated circuit configuration. In addition, since an MEMS device is a single structure that does not include an insulating layer, a single signal is applied to one structure, thereby simplifying driving, and all the driving electrodes of both ends thereof are driven so as to double a change in variable capacitance, thereby improving sensing ability.
