20100251537 | Through-Wafer Interconnections in Electrostatic Transducer and Array - A method for fabricating electrostatic transducers and arrays electrically separates the substrate segments of the transducer elements from each other using a technique involving two cutting steps, in which the first step forms a patterned opening in the substrate to make a partial separation of substrate segments, and the second step completes the separation after the substrate segments have been secured to prevent instability of the substrate segments upon completion of the second step. The securing of the substrate segments may be accomplished by filling a nonconductive material in the partial separation or securing the transducer array on a support substrate. When the substrate is conductive, the separated substrate segments serve as separate bottom electrodes that can be individually addressed. The method is especially useful for fabricating ID transducer arrays. | 10-07-2010 |
20110209337 | ELECTROACTIVE POLYMER PRE-STRAIN - The present invention provides electroactive polymers, transducers and devices that maintain pre-strain in one or more portions of an electroactive polymer. Electroactive polymers described herein may include a pre-strained portion and a stiffened portion configured to maintain pre-strain in the pre-strained portion. One fabrication technique applies pre-strain to a partially cured electroactive polymer. The partially cured polymer is then further cured to stiffen and maintain the pre-strain. In another fabrication technique, a support layer is coupled to the polymer that maintains pre-strain in a portion of an electroactive polymer. Another embodiment of the invention cures a polymer precursor to maintain pre-strain in an electroactive polymer. | 09-01-2011 |
20120304452 | METHOD OF MAKING A DUAL PORT PRESSURE SENSOR - A method of forming a dual port pressure sensor includes forming a first opening and a second opening in a flag of a lead frame. An encapsulant is molded to hold the lead frame in which the encapsulant is over a top of the flag and a bottom of the flag is uncovered by the encapsulant. A first opening in the encapsulant is aligned with and larger than the first opening in the flag and a second opening in the encapsulant aligned with the second opening in the flag. A pressure sensor transducer is attached to the bottom of the flag to cover the first opening in the flag, wherein the pressure sensor transducer provides an electrically detectable correlation to a pressure differential based on a first pressure received on its top side and a second pressure received on its bottom side. An integrated circuit is attached to the bottom of the flag. The integrated circuit is electrically coupled to the pressure sensor. A lid is attached to the encapsulant to form an enclosure around the bottom of the flag. The pressure sensor transducer receives the first pressure through the first opening in the encapsulant and the first opening in the flag and the second pressure through the second opening in the encapsulant, the second opening in the flag, and the enclosure. | 12-06-2012 |
