    Abstract: A multimodal haptic device includes a matrix incorporating at least one cell, each cell comprising: at least one thermal element capable of generating a cooling and a heating; at least one vibratory element capable of generating a vibration; and at least one encapsulation layer made of an electrically insulating material; the at least one vibratory element and the at least one thermal element being anchored in at least one part in the at least one encapsulation layer; each cell being adapted to be in contact directly or indirectly with the skin of a person so as to transmit thermal and/or vibratory sensations to that person, the cell having a thickness less than or equal to ten millimetres.

    Abstract: Flexible haptic interface including a chamber containing a non-newtonian fluid and bounded at least partially by a flexible wall the exterior face of which defines a touch surface capable of being touched by a user; a plurality of actuators borne by a flexible carrier and placed so as to transmit a local mechanical excitation to the fluid; and a control circuit connected to the actuators and configured to modulate the signals sent to the actuators in order to mechanically induce a modification of the rheology of the fluid and to generate a haptic sensation perceptible by the user on the touch surface.

    Abstract: A haptic interface of the ‘mid-air’ type, including a control circuit, a plurality of ultrasonic transducers connected to the circuit, which includes a first set of transducers emitting at a first ultrasound carrier frequency and at least a second set of transducers emitting at a second ultrasound carrier frequency different from the first; the control circuit being configured for modulating the signals sent to the transducers in order to generate, with the ultrasound waves emitted by at least a part of the transducers of the first set, an acoustic pressure detectable by touch within at least a first focal region, and generate, with the ultrasound waves emitted by at least a part of the transducers of the second set, an acoustic pressure detectable by touch within at least a second focal region.
