    摘要: An ultrasonic sensor which has a thin planar sheet of material forming a Lamb wave propagation medium, the sheet having a thickness which is no greater than about twenty microns. The sensor also includes a Lamb wave generator for generating Lamb waves in the propagation medium and an output device for producing an electrical signal representative of the propagation characteristics of the Lamb waves propagating along the propagation medium. A measuring device is included in the sensor to measure selected characteristics of the output electrical signal. The propagation medium has some physical characteristics that are determined by the value of a measurand acting on the medium and the determined physical characteristics determine the propagation characteristics of the Lamb waves which are propagated along the medium. When the sensor is acted on by a measurand to determine the physical characteristics of the propagation medium, the characteristics of the electrical signal are also determined. The measuring device measures the electrical signal and provides an indication of the measurand value. Several sensing arrangements are also disclosed as well as methods for making the planar propagation medium.

    摘要: Improved lithographic type microelectronic spring structures and methods are disclosed, for providing improved tip height over a substrate, an improved elastic range, increased strength and reliability, and increased spring rates. The improved structures are suitable for being formed from a single integrated layer (or series of layers) deposited over a molded sacrificial substrate, thus avoiding multiple stepped lithographic layers and reducing manufacturing costs. In particular, lithographic structures that are contoured in the z-direction are disclosed, for achieving the foregoing improvements. For example, structures having a U-shaped cross-section, a V-shaped cross-section, and/or one or more ribs running along a length of the spring are disclosed. The present invention additionally provides a lithographic type spring contact that is corrugated to increase its effective length and elastic range and to reduce its footprint over a substrate, and springs which are contoured in plan view. The present invention further provides combination (both series and parallel) electrical contacts tips for lithographic type microelectronic spring structures. The microelectronic spring structures according to the present invention are particularly useful for making very fine pitch arrays of electrical connectors for use with integrated circuits and other substrate-mounted electronic devices, because their performance characteristics are enhanced, while at the same time, they may be manufactured at greatly reduced costs compared to other lithographic type microelectronic spring structures.
