'Liquid pistons' – the next phone camera revolution?

Researchers at Rensselear Polytechnic Institute have developed "liquid pistons" that could be suited to a variety of applications. Using electromagnets the liquid pistons, which are highly tunable, scalable and have no solid moving parts, can function as pumps for lab-on-a-chip systems or could be used for adaptive lenses in future mobile phone cameras and implantable lenses.
