Polymer-coated contact lenses transform into next-gen electronics
Scientists from Future Industries Institute (FII) of University of South Australia have completed research on polymer film coating, which can conduct electricity on a contact lens and possibly integrate electrical circuits that are safe for human wear. This breakthrough could provide one of the safest methods of bringing people and their smartdevices closer together, according to FII associate professor, Drew Evans.
The conductive polymer used in the study is poly (3,4-ethylenedioxythiophene) (PEDOT) deposited from vapour phase onto hydrated hydrogel substrates, which were further plasma-treated for providing better adhesive property.
Researchers also seek to produce medical benefits through biocompatible conducting polymers at nano-scale and grow these directly on a contact lens.
