SMARTPRO.
Lightweight, flexible and smart protective clothing for law enforcement personnel.

SMARTPRO will develop lightweight and flexible protective clothing, incorporating smart functionalities, designated for daily use by law enforcement authorities.

Modern body armours still have some drawbacks, as they are mostly heavy, bulky and rigid. Therefore they limit the wearer’s mobility and agilityand are impractical for use on joints, arms, legs, etc. Moreover, body armours have traditionally been designed toprotect the wearer against ballistic threats and, thus, they provide only a limited level of protection against knives,sharp blades or sharp-tipped weapons. However, stab and puncture have become amain cause of police officers' injuries. Therefore, there is an obvious need to develop materials that combine staband ballistic protection, while retaining their flexibility and low weight.
In this context SMARTPRO aims to develop optimized ballistic textiles (both woven and spacer knittedfabrics) and apply innovative surface treatments (e.g. shear thickening fluids, ceramic coatings) to improve theirperformance on an areal density basis. Thus, fewer fabric layers will be required, which is expected to result inincreased flexibility and reduced weight of the armour. Main parameters to consider also include physiologicalcomfort and ergonomic design.
Additionally, smart functions, including positioning systems, will be integrated to further increase the efficiency of the body armour, eventually leading to reduced casualties. Finally, while a main limitation is that existing protective gear is usually limited to the body armour; innovativesolutions are herein proposed for the protection of vulnerable body parts other than the torso.

The first liquid armour

Achilles was the son of the Nereid Thetis and Peleus, the king of the Myrmidons. Zeus and Poseidon had been rivals for the hand of Thetis until Prometheus, the fore-thinker, warned Zeus of a prophecy that Thetis would bear a son greater than his father. For this reason, the two gods withdrew their pursuit, and had her wed Peleus

According to the Achilleid, written by Statius in the 1st century AD, and to no surviving previous sources, when Achilles was born Thetis tried to make him immortal, by dipping him in the river Styx. However, he was left vulnerable at the part of the body by which she held him, his heel. It is not clear if this version of events was known earlier. In another version of this story, Thetis anointed the boy in ambrosia and put him on top of a fire, to burn away the mortal parts of his body. She was interrupted by Peleus and abandoned both father and son in a rage
