Abstract (en)
[origin: EP2091269A2] The device (100) has an electric acoustics converter (110) receiving an acoustics wave and converting into an electric signal. Another electro acoustics converter (130) converts the signal into the wave. Electronic circuits (120, 140) and an electric energy source (150) i.e. battery, are sealed against fluid by plating and sealing. The electric acoustics converters e.g. flexural resonator, are designed from a material, which changes deformation into electric and/or magnetic field and/or electric current and/or electric voltage, and is insensitive against the fluid. The electro acoustics converters are selected from piezoelectric converters such as flexural resonator and thick oscillator.
