Abstract
The present invention relates to microstructures fabricated from semiconductor material and having a flexible member which is excited into various modes of resonance and in which such resonance is read optically. By coupling the microstructure to a surface or material of interest, a drive means will excite the flexible member into a characteristic resonance which when read optically gives indication of certain physical phenomena influencing the surface or material of interest. The microstructures of the present invention may be configured to self-resonate, as a so-called active device, under certain conditions. Many different physical phenomena may be quantified using the device of the present invention.
