Abstract
The invention relates to an accelerometer comprising at least one elastic plate propagating elastic surface waves, to which a normal force is applied resulting from the action of the acceleration which is to be measured on a solid or liquid body of predetermined mass. The measurement of the deviation in frequency of the oscillator of which the plate is a part gives an indication of the value of the normal component of the acceleration.
