Abstract
A force sensor including: a first part including a detection coil; a second part positioned opposite the first part and including: a ferromagnetic plate translationally movable relative to the first part to move towards the first part when a force is transferred to the sensor and to reduce reluctance of a magnetic circuit formed by the first and second parts in series with a variable gap; and an electronic detection circuit configured to generate a signal dependent on the reluctance of the magnetic circuit. The ferromagnetic plate is formed by an amorphous metal alloy.
