    摘要: The invention relates to a sensor (1) and a method for measuring pressure, variation in sound pressure, a magnetic field, acceleration, vibration, or the composition of a gas. The sensor (1) comprises an ultrasound transmitter (2), and a cavity (4) arranged in connection with it. According to the invention, the sensor (1) comprises a passive sensor element (3, 3′) located at the opposite end of the cavity (4) to the ultrasound transmitter (2), the distance of which from the ultrasound transmitter (2) is selected in such a way that the resonance condition is met at the ultrasound frequency used, the ultrasound transmitter (2) comprises a light-construction diaphragm oscillator (9), which is thus well connected to the surrounding medium, and the sensor includes means for measuring the interaction between the ultrasound transmitter (2) and the cavity (4).

    摘要: Sonication of a medium for example in an immunassay is provided by applying sound waves from a transducer to a vessel in which the medium is held by a sonotrode coupled between the transducer and the vessel. The sonotrode has a recess in which the vessel is held, the recess being formed by facing surfaces of a plurality of protruding portions of the sonotrode separated by slits and arranged around the recess. The sonotrode is coupled to the vessel by dry contact with the vessel without any coupling layers therebetween. The use of such a sonotrode provides the advantages of allowing effective sonication with relatively low energy loss and with a low temperature elevation.
