    摘要： A differential pressure sensor for use in an industrial application is described. The differential pressure sensor includes a membrane layer having a covered portion and an exposed portion where a first side of the exposed portion of the membrane layer is in fluid communication to a first aperture and a second side of the exposed portion is in fluid communication to a second aperture. The differential pressure sensor also includes at least one resonating device secured to the covered portion of the membrane layer and configured to oscillate at a desired frequency and a sensing circuitry configured to a detect oscillation in the at least one resonating device indicative of deformation in the membrane layer.

    摘要： A device, such as a switch structure, is provided. The switch structure can include a contact and a conductive element each respectively disposed on a substrate. The conductive element can be composed substantially of metallic material, and can be configured to be deformable between a first position, in which the conductive element is separated from the contact by a separation distance, and a second position, in which the conductive element contacts the contact and stores mechanical energy. The conductive element can be further configured such that, subsequent to being deformed into the second position at a temperature between about room temperature and about half of a melting temperature of the metallic material for a cumulative time of at least 107 seconds, the separation distance in the absence of external forces varies by less than 20 percent over the cumulative time. Associated methods are also provided.

    摘要： A micro-electro-mechanical, micro-fluidic flow sensor (14) includes a flow separating element (15) for separating a first portion (24) of a fluid flow (25) from a second portion (26) of the fluid flow. The flow sensor also includes a flow obstructing member (17) disposed in the first portion of the flow for at least partially obstructing the first portion of the flow. The flow obstructing member deflects in response to the first portion of the flow so that a degree of partial obstruction of the first portion of the flow by the flow obstructing member varies in response to the first portion of the fluid flow.
