prototype suit Proetex situations of danger such as fire, flood, earthquake areas and interventions in the presence of toxic clouds, raise particular concerns for the protection of worker safety and civil protection brigade Fire the face. Rescuers come to the aid of the project Proetex , funded for 12 million euro from the EU. The goal is to create garments with sensors, able to monitor the physical and environmental conditions of staff working in these critical situations, and ensuring their safety. The involvement of 23 international partners, including, for Italy 's Eucentre of Pavia, Research Centre of Civil Protection, will make available by 2010 common clothing which, thanks to nanotechnology , are both life-saving suits that control the heart rate and respiration rate of those who face emergency situations, in addition to their posture and the chemical composition of the sweat and blood, to assess the level of stress and dehydration. The suits also occur intelligent ambient temperature, identifying the possible presence of toxic gases and vapors in the air, data periodically communicated to a receiving center that helpers operators in cases of proven danger. The project involves the construction of three prototypes, the first of which has already been completed, while in France is now being tested in the second. "Of the 23 partners involved in project, some are institutional, like the body of firefighters in Paris, other manufacturers, "explains Professor Panorama.it Gian Michele Calvi, President dell'Eucentre, adding that" Italy is responsible for part of the scientific development concept and the project, prior to the possible marketing of products in 2010, and based on three prototypes that do not differ radically from each other, but represent a continuous development and refinement of a single project. " The overall life-saving development at different stages of this project will consist of three pieces of clothing: a T-shirt in cotton underwear, washable and reusable, integrating textile electrodes and sensors to monitor heart rate, respiratory and body temperature, it is worn on a fireproof jacket, shirt with a physically combined with the cable necessary for the transmission of data collected from sensors , which simultaneously provides the power supply, made by special rechargeable batteries contained in the jacket itself. In the lining of the latter, with a temperature sensor, a GPS module locates the rescuer, and two accelerometers , placed in the collar to the left wrist, it identifies the level of activity. In a pocket built below the inner layer, the space is also questioning the electronic network of sensors, such as mesh jacket, transmitting the readings to a software installed on a remote computer, where they are captured by the coordinator of 'intervention, and can be viewed online for the production of alarms (if the sensors detect danger to the operator), as well as saved into text files for later analysis. The transmission of data recorded by the sensors is ensured by a Bluetooth module combined with aerial fabric sewn into the lining of his jacket. To complete the overall a pair of boots, fire resistant, with pockets and compartments designed so as to permit the development of the project, the further integration of sensors and processing devices and data transmission. "In this way," says Calvi, "the mobile laboratory that follows the intervention in areas at risk, in fact, a truck will have all the data to determine how an operator, for example, is grappling with a fire, can remain in a given situation before it becomes too dangerous, or whether he is in difficulty, indicated by sudden changes in posture. " All at no cost too high: "In similar projects cost more than the hardware software, or is more expensive to ensure the robustness and stability of the system, which can not give room for error, while the low cost of the sensors will not rise that much of the clothing in which they are integrated, "
