American experts are working on a new kind of technology that could be used in, for instance, in the production of contact lenses boosting drug delivery.
Researchers at the Rensselaer Polytechnic Institute in New York informed that the liquid pistons that they have developed contain oscillating droplets of ferrofluid. These droplets can be utilised to pump little amounts of various liquids. In addition, the scientists strongly believe that the technology they are testing may be used to produce improved mobile phone cameras, advanced medical equipment (especially imaging devices), drug delivery devices and replacement eye lenses that can be implanted in the human body.
The research project is supervised by Professor Amir Hirsa, who stated that their electromagnetic liquid pistons presented a new method of dealing with the challenge of microscale liquid pumping and that it had been demonstrated how these pistons are appropriate for use in chip-level, fast acting adaptive lenses.
