Abstract: A MEMS device comprises a suspended membrane structure having an inner membrane section and an outer membrane section. The outer membrane section surrounds the inner membrane section. The membrane structure comprises an elastically deformable spring structure in the outer membrane section, such that the spring structure is arranged to convert a thermal-induced compressive stress in the suspended membrane structure into a spring displacement.
