1. A multimodal haptic device comprising a matrix incorporating at least one cell, each cell comprising:
at least one thermal element to generate a cooling and a heating;
at least one vibratory element to generate 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 said at least one encapsulation layer;
each cell being adapted to be in contact directly or indirectly with the skin of a person such that said at least one thermal element is able to transmit thermal sensations to that person and such that at least one vibratory element is able to transmit vibratory sensations to that person, said cell having a thickness less than or equal to ten millimetres, the at least one thermal element having a height greater than that of the at least one vibratory element.
