Abstract: An improved high voltage MEMS, and a portable ultrasound device comprising such a MEMS, and use of such a portable device for detecting a liquid volume. Microelectromechanical systems (MEMS) relate to a technology of very small devices.

Abstract: A MEMS pressure sensor wherein at least one of the electrode arrangements comprises an inner electrode and an outer electrode arranged around the inner electrode. The capacitances associated with the inner electrode and the outer electrode are independently measured and can be differentially measured. This arrangement enables various different read out schemes to be implemented and also enables improved compensation for variations between devices or changes in device characteristics over time.

Abstract: One or more embodiments provide circuitry for isolation and communication of signals between circuits operating in different voltage domains using capacitive coupling. The embodiments utilize capacitive structures having increased breakdown voltage in comparison to previous parallel plate implementations. The capacitive isolation is provided by parallel plate capacitive structures, each implemented to have parallel plates of different horizontal sizes. Due to the difference in horizontal size, edges of the parallel plates, where electric fields are the strongest, are laterally offset from the region where the parallel plates overlap. As a result, breakdown voltage between the parallel plates is increased.

Abstract: A capacitive sensor is configured for collapsed mode, e.g. for measuring sound or pressure, wherein the moveable element is partitioned into smaller sections. The capacitive sensor provides increased signal to noise ratio.
