1. An electromechanical sensor comprising:
a base provided with a magnetic sensor arranged to detect a change in magnetic flux at the position of the magnetic sensor;
a flexible film adjacent to the magnetic sensor; and
a magnetic element provided on the flexible film;
wherein the magnetic element is arranged to move relative to the magnetic sensor when the flexible film is reversibly deformed by an external force applied to the flexible film.
