摘要: A micromechanical sensor unit, including: a substrate and an edge layer, which is situated on the substrate and laterally frames an inner area above the substrate; at least one diaphragm, which spans the inner area and forms a covered cavity above the substrate; at least one support point, which is situated between the substrate and the diaphragm inside the cavity and attaches the diaphragm to the edge layer and/or to the at least one support point. The support point separates the diaphragm into at least one measuring area that is movable through force action and at least one reference area that is not movable through force action. The substrate and the diaphragm, inside the cavity, include electrodes, which face one another in the measuring area and the reference area.

摘要: A microelectromechanical resonator includes a support structure, a resonator element suspended to the support structure, and an actuator for exciting the resonator element to a resonance mode. The resonator element includes a plurality of adjacent sub-elements each having a length and a width and a length-to-width aspect ratio of higher than 1 and being adapted to a resonate in a length-extensional, torsional or flexural resonance mode. Further, each of the sub-elements is coupled to at least one other sub-element by one or more connection elements coupled to non-nodal points of the of said resonance modes of the sub-elements for exciting the resonator element into a collective resonance mode.

摘要: A microelectromechanical system (MEMS) actuator device includes a substrate; a shape memory alloy over the substrate; and a reflective coating on the shape memory alloy. The shape memory alloy and the reflective coating form a bi-layer cantilever beam having a first end anchored to the substrate, and a second end released from the substrate. The second end of the cantilever beam articulates between a deflection configuration away from the substrate and a non-deflection configuration towards the substrate based on a thermal phase change in the shape memory alloy.

摘要: The present invention discloses a bionic SERS substrate of a metal-based compound eye bowl structure, a construction method and application. The bionic SERS substrate of the metal-based compound eye bowl structure of the present invention consists of a metal bowl and a cone-shaped structure substrate in an ordered hierarchy manner. The metal bowl is of a continuously and closely arranged single-layer bowl structure. A height of the metal bowl is 0.01-10 μm, and a bowl opening diameter is 0.01-10 μm. A cone is a micron pyramid cone, and a height of the micron pyramid cone is 1-100 μm. The present invention assembles the metal bowl on a surface of the substrate of the micron pyramid cone structure with great fluctuation by a solid-liquid interface chemical reduction method and a small ball template method, and further constructs a 3D SERS substrate with a bionic compound eye structure.
