Abstract
An electric transducer for measuring mechanical quantities comprises a movable tongue which is acted upon by the mechanical quantity to be measured and the deflection of which is converted into an electrical signal. The tip of the tongue may be designed as the gate and an electric conduction channel disposed opposite the tip at a small distance therefrom may comprise the source-drain path of a field effect transistor, or vice versa.
