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. Further, the MEMS device applies a thermal scheme which performs an automatic focusing function through vertical operation of a lens by a thermal expansion difference of different materials, thereby simplifying the structure thereof and reducing the cost.
