摘要： A bistable electroactive polymer transducer is provided for electrically actuated deformation of rigid electroactive polymer members. The polymers have glass transition temperatures (Tg) above ambient conditions and turn into rubbery elastomers above Tg and have high dielectric breakdown strength in the rubbery state. They can be electrically deformed to various rigid shapes with maximum strain greater than 100% and as high as 400%. The actuation is made bistable by cooling below Tg to preserve the deformation. The dielectric actuation mechanism includes a pair of compliant electrodes in contact with a dielectric elastomer which deforms when a voltage bias is applied between the pair of electrodes. In some of the transducers of the present invention, the dielectric elastomer is also a shape memory polymer. The deformations of such bistable electroactive polymers can be repeated rapidly for numerous cycles. The polymer transducers have such advantages as high energy and power densities, quietness, mechanical compliancy (for shock resistance and impedance matching), high efficiency, lightweight, and low cost.

摘要： Provided is a method of fabricating a piezoelectric microspeaker. According to the method, drive units having a piezoelectric layer and an electrode are symmetrically formed so as to be disposed over and under a diaphragm, respectively. When a thin conductive layer is used as the diaphragm, the diaphragm can be used as a common electrode. On the other hand, when a thin non-conductive layer is used as the diaphragm, a common electrode is necessary in each of the drive units.

摘要： Systems and methods for promoting a substantially uniform cavitation field. With system (100) including a diaphragm (109) dividing a container (103), a second energy pulse corresponding to a first energy pulse arising from collapse of a cavity C is produced and is used to determine whether to adjust a corresponding transducer 121-k. In system (16), a cavity creating unit (11), including an assembly of transducers 15-i, is moveable from a test liquid to a particle removal (PR) liquid after transducer testing. In another system, a sensor plate (170) having an array of sensors 171-j provides a virtual wafer. A substantially uniform field of cavitation may be maintained by a cavity enhancement liquid, or adjustment of transducer energy. Mechanisms of holding an object produce substantially uniform cavitation. Opposed transducers in a container having monotonically decreasing and/or increasing cavitation density produce substantially uniform cavitation density.

摘要： An arrangement for reducing piezo-electric effects in piezo-electric effect sensitive electrical components formed in a semiconductor body is disclosed. The piezo-electric effect sensitive component or components are located in a particular zone of the semiconductor body. The semiconductor body is in general mounted on a support. However, the zone of the semiconductor body containing the piezo-electric sensitive component or components is not attached to the support but instead is separated from the support by a space. The presence of the space results in a certain degree of mechanical isolation of the part of the semiconductor body which contains the piezo-electric effect sensitive components, whereby the negative influence of the piezo-electric effect on the long term stability of an instrument utilizing the semiconductor body is reduced.
