This paper illustrates the results obtained at Composite and Smart Materials Laboratory of Politecnico di Milano by an industrial-academic team, that designed, developed and produced a technological demonstrator for space structures, embedding piezoelectric sensors/actuators and optical sensors. The selection of optical sensors, the use of PZT material, and their embedding techniques into composite laminates are described in the following, as well as embedding a sensing/actuation pack, i.e. robust and easy to handle sensor\actuator unit, in the demonstrator structure. Finally, actuation/sensing capability have been tested to validate both the embedded sensors/actuators and the technologies adopted for the manufacturing process.
