  • Publication number: 20210114699
    Abstract: The invention relates to a method for determining the direction and the amplitude of a force applied to a system (IO) comprising a stationary portion (13) and a mobile portion (12) which can deform when exposed to said force. Mechanical deformations applied to the mobile portion when exposed to said force are measured by measuring a distance between the stationary portion and the mobile portion in the direction of application of the force, and the distance measurements are processed in order to determine the amplitude and the direction of the force.
