    Abstract: An integrated piezo-resistive sensor for determining mirror position in an optical switch. One or more piezo-resistive layers may be formed in silicon springs supporting a movable mirror in the switch. Change in resistivity of those layers due to spring deformation during mirror motion is measured and related to the mirror deflection angle. Information about the angle may be used to provide feedback to the motion actuator, which then may be operated to orient the mirror more accurately. A sensor's sensitivity may be increased by appropriately orienting the springs with respect to the crystallographic axes of the silicon.

    Abstract: The invention relates to devices and methods for detecting a ligand in a liquid, based on deflection of one or more microscopic cantilevers. Each cantilever has an optical waveguide fixed thereto or integral therewith. Deflection of the cantilever is detected by assessing coupling of light between the optical waveguide on the cantilever and an optical waveguide fixed distally thereto.

    Abstract: A semiconductor structure includes a substrate, a sacrificial layer formed on or over the substrate, and a structural layer formed on or over the sacrificial layer. At least one opening is formed in the structural layer. At least one opening is formed in the sacrificial layer below the at least one opening in the structural layer. The at least one opening in the structural layer and the at least one opening in the sacrificial layer are at least partially filled with a filler material. At least one portion of the structural layer is removed to define at least one microstructure. The sacrificial layer is removed such that the at least one microstructure is released from the substrate and the filler material forms one or more protrusions on the at least one microstructure, and/or one or more anchors anchoring the at least one microstructure to the substrate.
