Abstract: A transducer array for ultrasound applications includes a plurality of transducer elements that are provided with self-aligned connections to a flexible cable. The array is easy to manufacture and suited for wearable, wireless, and other small ultrasound devices. A simple and efficient method of producing a robust transducer array involves at least partially separating the transducer elements after their connection to their respective conductors.

Abstract: A wearable ultrasound device for signalling changes in human or animal body, and use of such a wearable device for signalling over a prolonged period of time. In an example the changes occur in a bladder. Such is especially relevant for elderly persons, women after delivery of a baby, lesion patients, demented people, children, and others, have a difficulty to control functioning of the bladder, and to be at the toilet on time to urinate.

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. Piezoelectricity relates at one hand to accumulation of electric charge in certain solid materials in response to an applied mechanical stress.
