    摘要: A thermal actuator comprises a substantially straight beam. The beam has a beam length and a beam mid-point. The beam comprises a plurality of beam segments. Each beam segment has a beam segment width, the beam thus forming a corresponding plurality of beam segment widths. The beam segment widths vary along the beam length based on a predetermined pattern. As the beam is heated by an included heating means, the beam buckles. The buckling of the beam, in turn, causes the beam mid-point to translate or move in a predetermined direction. The beam mid-point movement, in turn, operates an included optical waveguide switch. The heating means comprises any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

    摘要: A microstructure that may be used as an electrical connection in a microfabricated electro-mechanical system (MEMS) apparatus. The microstructure may have one or more isolatable electrical connections for signal transmission. The microstructure allows a MEMS apparatus to shield signal transmissions from the effects of electromagnetic interference or conductive fluids.
