Abstract (en)
[origin: WO2011051040A1] The invention relates to an ultrasound transducer (110) for using in a fluid medium (116). The ultrasound transducer (110) comprises at least one transducer core (118) with at least one acoustic-electric transducer element (112), especially a piezoelectric transducer element (112). The ultrasound transducer (110) comprises at least one housing (120), at least one housing opening (122) being at least partially sealed from the fluid medium (116) by a sealing film (130) connected to the transducer core (118). The sealing film (130) comprises at least one expansion deformation (134) designed to enable a relative movement between the transducer core (118) and the housing (120).
