  • Vibrotactile actuator
    Patent number: 11289988
    Abstract: A vibrotactile actuator includes a network of flat electromagnetic coils positioned contiguously in a plane, the network of coils being able to generate a Laplace force under the effect of an electric current passing through the network of coils, a network of permanent magnets assembled linearly in a plane parallel to the plane of the network of coils and forming a Halbach network generating magnetic field lines oriented towards the network of coils, an electromagnetic interaction between the current lines passing through the network of coils and the magnetic field lines giving rise, as a result of the Laplace force, to relative translational movement between the network of coils and the network of magnets, and an elastic guide device for generating haptic vibrations from the relative translational movements of the network of coils and the network of magnets.
