    摘要： The present invention relates to a transducer arrangement, particularly a transducer arrangement for acquiring tissue information, a method for using a transducer arrangement for acquiring tissue information and a glove which comprises a transducer arrangement. The transducer arrangement 21 for analysing material 40 comprises: a first transducer element 51 for inducing and receiving mechanical displacements in the material to be analysed 40; and an analysing unit 30. The transducer arrangement is arranged such as to be flexible in order to conform with a curved surface of the material to be analysed 40; and the transducer arrangement 21 is adapted to derive a first signal from a low frequency spectrum of mechanical displacements which first signal correlates to sono-elastographical properties of a material to be analysed 40; and the transducer arrangement 21 is adapted to derive a second signal from a high frequency spectrum of mechanical displacements received by the first transducer element 51 which second signal correlates to ultrasonic properties of a material to be analysed 40. With a transducer arrangement according to the invention it may be possible to generate information about the topographical anatomy and information about elastical properties of the material to be analyzed in parallel, whereby the transducer arrangement may be adapted to the unevenness of the material's surface optimally due to its flexibility which may allow the examiner or user of the transducer arrangement to analyze regions which normally may have an uneven surface profile, which may only be reached with difficulty or whose examination may cause inconvenience to the examiner as well as to the person that is being examined.

    摘要： The present invention relates to an electric component comprising at least one first MIM capacitor having a ferroelectric insulator with a dielectric constant of at least 100 between a first capacitor electrode of a first electrode material and a second capacitor electrode of a second electrode material. The first and second electrode materials are selected such that the first MIM capacitor exhibits, as a function of a DC voltage applicable between the first and second electrodes, an asymmetric capacity hysteresis that lets the first MIM capacitor, in absence of the DC voltage, assume one of at least two possible distinct capacitance values, in dependence on a polarity of a switching voltage last applied to the capacitor, the switching voltage having an amount larger than a threshold-voltage amount. The invention is applicable for ESD sensors, memories and high-frequency devices.

The transducer further includes a layer of a high dielectric constant material disposed between the third electrode and the first electrode, and between the third electrode and the second electrode. The transducer may be operable in a collapsed mode wherein the peripheral region of the third electrode oscillates relative to the second electrode, and the central region of the third electrode is fully collapsed with respect to the first electrode such that the dielectric layer is sandwiched therebetween. Piezoelectric actuation, such as d31 and d33 mode piezoelectric actuation, may further be included. A medical imaging system includes an array of such capacitive ultrasound transducers disposed on a common substrate.

    摘要： The present invention relates to a ferroelectric varactor (400) that comprises a dielectric-layer stack (408) between electrodes (406, 410). The dielectric-layer stack comprises an alternating layer sequence of at least three dielectric layers. At cc least two first dielectric layers of the dielectric-layer stack are made of a non-single-crystalline first dielectric material having a first dielectric constant, at least one second dielectric layer of the dielectric-layer stack is made of a non-single-crystalline second dielectric material with a second dielectric constant that differs from the first dielectric constant. One of the first and second dielectric materials exhibits a weaker ferroelectric hysteresis. The dielectric material with the weaker ferroelectric hysteresis makes up more than 20% of the total volume of the dielectric-layer stack. The ferroelectric varactor of the present invention achieves high relative dielectric permittivities in the dielectric layers, a high breakdown voltage, a large tuning range at low voltages, and low dielectric losses.
