APPARATUS FOR PROVIDING A FLUID MENISCUS WITH VARIABLE CONFIGURATIONS BY MEANS OF ELECTROWETTING APPARATUS COMPRISING AN IMAGE SENSOR AND MEDICAL IMAGING APPARATUS

摘要

The present invention relates to an apparatus for providing a fluid meniscus having a variable configuration by electrowetting. The fluid chamber 5 holds two different fluids A, B separated by the meniscus 14 whose edges with different sides are constrained by the fluid chamber. The first electrowetting electrode 2a is arranged to act on the first side of the meniscus edge, and the second electrowetting electrode 2a 'is arranged to act separately on the second side of the meniscus edge. . The selected meniscus configuration can be formed by providing the selected voltage to the first and second electrowetting electrodes, respectively.
