New 'smart contact lenses' double up as personal physicians on move
Scientists have developed an ultra-flexible and transparent electronic circuit that could be used in the production of smart contact lenses.
The Swiss scientists at ETH Zurich, have created the circuit with parylene, which was deposited onto vinyl polymer, before printing on to the parylene, Mashable reported.
The chip is then submerged into water, which dissolves the polymer, leaving behind just the circuit.
Researchers are currently investigating the medical benefits that this kind of technology can offer, such as monitoring intraocular pressure for glaucoma disease.
Scientists have tested the circuit on an artificial eye, but more research is need before the product hits the market and would require other components, including long-lasting batteries and sensors, to function outside of the lab.
The study was published in the journal Nature Communications.
