A new type of technology developed by experts in the US may lead to the creation of adaptive contact lenses which can boost drug delivery.
According to engineering researchers at Rensselaer Polytechnic Institute in New York, the liquid pistons contain oscillating droplets of ferrofluid which can be used to pump small volumes of liquid.
They claim that this method could be utilised to enhance the development of mobile phone cameras, medical imaging equipment, implantable drug delivery devices and implantable eye lenses.
Professor Amir Hirsa, who led the research, commented: "Our electromagnetic liquid pistons present a new strategy for tackling the challenge of microscale liquid pumping.
"Additionally, we have shown how these pistons are well-suited for chip-level, fast-acting adaptive liquid lenses."
