    摘要: The invention provides a device for the gravimetric detection of particles in a fluid medium, comprising a flat electromechanical oscillator (1), means for supporting the oscillator, means (15a, 15b, 15c, 15d) for actuating said oscillator and, on either side of the plane of the oscillator (1), two cavities (3, 5) enabling the oscillator (1) to vibrate when it is activated by the actuation means (15a, 15b, 15c, 15d), characterized in that at least one of the two cavities (3, 5) forms an integral part of a channel (2, 4) for the passage of a fluid over at least one of the faces (1a, 1b) of the oscillator and in that said actuation means (15a, 15b, 15c, 15d) take the form of at least one electrode (15a, 15b, 15c, 15d) lying in the same plane as that of the electromechanical oscillator and at a defined distance (g) from the oscillator, so as to ensure that the oscillator vibrates in its plane.
