Abstract: A method for manufacturing a 3D mechatronic object having predetermined mechatronic functions, which includes as components at least one sensor and/or one actuator, an electronic circuit connected to the sensor and/or to the actuator via electrically conductive tracks, these components positioned in a main mechanical structure, and which consists of multiple polymers having various electronic and/or electroactive properties, comprises the following steps: determining the polymers according to their melting temperature, chemical compatibility, electrical and/or electroactive properties; determining a 3D digital model of the object, including its shape and the routing of the tracks, on the basis of predetermined mechatronic functions of the object, properties of the polymers and specifications of the object; 3D-printing the sensor and/or the actuator, the electronic circuit and the main structure in the same modeling steps according to the generated model by depositing layers of the molten polymers, certain lay

Abstract: A haptic system for establishing an interaction between at least one part of the body of a user called stimulation zone and a virtual environment comprises means for estimating the position of the stimulation zone; means for emitting, toward the stimulation zone, at least one flow rate-controlled air jet, the air jet being emitted at a point of emission and its flow rate being determined as a function of the estimated position of the stimulation zone in space and of the characteristics of the virtual environment; a robotized structure controlled so as to move the point of emission of the air jet so that said point of emission remains at a constant distance from the stimulation zone.
