ABSTRACT:
A thermally buckling linear micro structure, in which by isolating technology a thermal oxidization isolation layer are generated on the two ends of a micro structure, or a material with larger thermal inflation coefficient is deposited, or the area of thermal conduction is reduced so that the two ends of a micro structure has a larger thermal stress and the membrane structure may be heated uniformly so to cause a thermally buckling deformation, therefore, the deformation of the membrane type micro structure is amplified linearly with the input power. This micro structure is formed as a membrane type by a membrane manufacturing technology.
