摘要： A gyroscope comprising: a proof mass; a frame supporting the proof mass; a connection arrangement connecting the proof mass and the frame, the connection arrangement having a first stiffness in a first direction and a second stiffness in a second direction substantially perpendicular to the first direction, one of the stiffness being significantly greater than the other stiffness; and a pair of elements adapted to sense relatively motion therebetween in either the first or the second direction. Also disclosed is a gyroscope comprising: a proof mass; a frame supporting the proof mass and connected to only one edge thereof by a connection arrangement extending between the proof mass and the frame in a first direction, the connection arrangement having a first stiffness in the first direction and a second stiffness in a second direction substantially perpendicular to the first direction, the first stiffness being significantly greater than the second stiffness; and a pair of elements adapted to sense relative motion therebetween in the first direction.

摘要： Thin films of ferroelectric material with a high mole fraction of Pb(A2+1/3B5+2/3)O3 substantially in a perovskite phase, wherein A is zinc or a combination of zinc and magnesium, and B is a valence 5 element such as niobium or tantalum, have been prepared. Typically, the mole fraction of Pb(A2+1/3B5+2/3)O3 in the ferroelectric material is >0.7. The method for preparing the thin films of ferroelectric material comprises providing a precursor solution containing lead, A2+, and B5+; modifying the precursor solution by addition of a polymer species thereto; applying the modified precursor solution to a surface of a substrate and forming a coating thereon; and (d) subjecting the coating to a heat treatment and forming the film in the perovskite phase. Optimal results have been obtained with PEG200 as the polymer species.

摘要： Ferroelectric Poly(vinylidene fluoride) Film on a Substrate and Method for its Formation A method of producing a poly(vinylidene fluoride) (“PVDF”) film on a substrate from a precursor solution is disclosed. The method comprises preparing the precursor solution for the PVDF film and dissolving an additive in the precursor solution, the additive being selected from the group consisting of: a hydrate salt, and a hygroscopic chemical. The PVDF is added to the precursor solution. The PVDF solution is coated on a substrate to form an as-deposited PVDF film which is dried and crystallized at an elevated temperature. The dried and crystallized as-deposited PVDF film is annealed at a further elevated temperature. The further elevated temperature is greater than the elevated temperature but less than a melting point of the as-deposited PVDF film. The additive dehydrates at the further elevated temperature. A corresponding product is also disclosed.

摘要翻译： 基板上的铁电性聚（偏二氟乙烯）膜及其形成方法公开了从前体溶液在基材上制备聚（偏二氟乙烯）（“PVDF”）膜的方法。 该方法包括制备用于PVDF膜的前体溶液并将添加剂溶解在前体溶液中，添加剂选自：水合物盐和吸湿性化合物。 将PVDF加入到前体溶液中。 将PVDF溶液涂覆在基材上以形成沉积的PVDF膜，其在高温下干燥并结晶。 干燥并结晶沉积的PVDF膜在进一步升高的温度下退火。 进一步升高的温度大于升高的温度但小于沉积的PVDF膜的熔点。 添加剂在进一步升高的温度下脱水。 还公开了相应的产品。
