    摘要： The invention relates to an electrowetting-on-dielectric device (200). This is an electro wetting device comprising one or more cells, wherein each cell comprises an electrowetting composition of first and second immiscible fluids, the first fluid being an electrolytic solution (240), a first electrode (230), separated from the electrowetting composition by a dielectric (231), and a voltage source (260) for applying an operating voltage difference between the first electrode (230) and the electrolytic solution to operate the electrowetting device. According to the invention, the first electrode (230) of the electrowetting-on-dielectric device (200) comprises a valve metal, and the electrolytic solution (240) is capable of anodizing the valve metal to form a metal oxide at the operating voltage difference. This provides the electrowetting-on-dielectric device (200) with self-repairing properties thereby preventing breakdown of the dielectric. As a result, the electrowetting device can be operated at a low voltage, and it has an improved reliability.

    摘要： Fluid lens system, e.g. for medical imaging or medical treatment, with a container enclosing a fluid arranged to refract incoming waves. A pressure release mechanism is in contact with the fluid so as to compensate changes in its volume due to thermal variations, e.g. during high temperature medical cleaning. This pressure release mechanism is positioned within a pathway of incoming waves. In preferred embodiments a fluid container connected via a tube to the fluid as a reservoir, is arranged within or outside the container, e.g. beyond an image sensor. Alternatively, an easily compressible body, e.g. a small closed metal bellows enclosing a gas, is positioned inside the fluid to absorb volume changes by compression. In both embodiments, the pressure release elements are preferably positioned in a peripheral part of the pathway of incoming waves to not affect performance of the lens. In another aspect, a fluid lens includes a container with an inner container part that fits inside an outer container part, wherein the inner container part is in rigid connection to at least a one boundary arranged for penetration of incoming waves. The pressure release mechanism is positioned within the outer container part, and it is in contact with the fluid so as to compensate changes in volume of the fluid due to thermal variations. In one embodiment the inner and outer container parts are arranged for relative one-dimensional movement and fluid tight interconnected. In another embodiment, a fluid filled cavity is formed between the inner and outer container parts, and this cavity houses a compressible body. The lens systems are suited for applications such as medical endoscopes, catheters and needles, optically as well as acoustically based.

    摘要： The invention relates to an acoustical switch wherein the idea to the ultrasound propagation direction may be changes without moving the switch. The switch device comprises two sheets of acoustically transparent material. The sheets constitute opposite walls of a housing. The switch device further comprises one or more orifices for allowing conduction of fluid into and/or out of said housing. The switch device may be made reflective by filling the housing with a gas via the one or more orifices. Moreover, the switch device may be made transmissive to ultrasound by filling the housing with a liquid via the one or more orifices and/or by subjecting the housing to underpressure via the one or more orifices. The acoustical switch device fits well within a catheter, which has severe dimensional limitations.
