    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 integrated capacitor structure comprises a first branch with a first capacitor (60) and a second branch with a second capacitor (70). The second capacitor (70) has a higher capacitance density and a lower breakdown voltage than the first capacitor (60). The first branch has a shorter RC time constant than the second branch, such that a voltage peak will substantially follow the first branch. This first capacitor (60) has a sufficient capacity to store the charge of the voltage peak. In one embodiment, the second capacitor (70) is a stacked capacitor. The structure is suitable for ESD-protection and may, to this end, additionally comprise diodes (21) and resistors (22).
