Abstract: The construction comprises a substrate (1), a barrier layer (2), a resistance layer (3), a dielectric layer (4) with a dielectric constant (K) (7), an electrode (5), a second dielectric layer (6) and a second electrode (7). This sandwich assembly is enclosed by terminals (8) to form a suppression filter. A track (9) passes through the dielectric layers, connecting the resistance layer and the top dielectric layer

Abstract: The invention relates to an array of ultrasound transducers which each comprise a membrane that is comprised of diamond or diamond-like carbon, a barrier structure, a piezoelectric layer, a first electrode and a second electrode. The barrier structure ensures strong adhesion of the piezoelectric layer to the barrier structure and thus to the device and that the piezoelectric layer only comprises a single phase. In addition, the barrier structure protects the membrane against oxidation/decomposition during the manufacturing process of piezoelectric layer. The invention further relates to an ultrasound transducer.

Abstract: An elongate device (e.g. a catheter) for interventional MRI has one or more passive LC-circuits (wireless markers) attached to its distal tip portion for position tracking. The LC-circuits comprise an inductor winding (480) and a three-dimensional "trench" capacitor (420-440) and are integrated in a piece of silicon (410). Optical fibres may be included in the device for optical probing of tissue surrounding the distal tip portion.
