Autonomous System matrix driver for the controlled distribution of active substances

The present invention relates to a matrix system (1) self-driven and for the controlled delivery and flexible only at appropriate times and precise at least one active substance characterized in that it comprises: - a non-layered polymer matrix ( 2) loaded in said active substance, - at least one heating element (4) embedded in said matrix (2) charged, said heating element (4) being adapted to heat homogeneously the whole of said matrix (2) so to temporarily dilate the polymeric network to cause the release of said active substance, and - a generator (5) of electrical current controlled by a control electronic circuit board housed in a electronic control unit (3).
