Introduction On Contract Lenses With Electronic Circuits

Though there are many different types of contact lenses available on the market

, have you ever imagined contact lenses with electronic circuits? You may think it will be a joke. But actually it is true. This kind of contact lenses with electronic circuits is invented by engineers from University of Washington. They are flexible, biologically safe contact lenses equipped with ID electronic circuit and lights. These contact lenses have several functions and the invention of them is a new achievement in this field.

First, let's know these great inventors. They are: Babab Parviz, who is an assistant professor of electrical engineering at UW; Harvey Ho, who a former graduate student of Parvizs and now working at Sandia National Laboratories in Livermore; Calif and Ehsan Saeedi and Samuel Kim. At the Institute of Electical and Electronics Engineers international conference on Micro Electro Mechanical Systems, which was held on Jan. 18, 2009, these engineers presented this new lens. And this novel contact lens with electronic circuits attracts worldwide attention.

It is said and proved contact lenses with electronic circuits have the following functions: First, they can give some help to those people with poor eyesight. Second, they can also play a role in holographic driving control panels and the way to surf the web on the go. Of course, these contact lenses also have some other functions which need people to prove them after their using.

As we know, this is not a simple task and the engineers are contributed a lot in it Thanks to their hard work that people will benefit a lot from them in the later usage. Engineers use inorganic materials, scorching temperatures and toxic chemicals to produce this kind of contact lens. Do you want to know how the circuits are built? The circuits are built from metal layers, which are only one thousandth the width of human hair and the light-emitting diodes are just one third of a millimeter across. The lenses with electronic circuits are realized by sprinkling grayish powder of electric components on a flexible plastic sheet.

Engineers made the test on rabbits for 20 minutes. And the result is there are no inauspicious effects on the rabbits. Though the contact lenses contain an electric circuit and red light-emitting diodes for a display, wearers can not notice them when they wearing this kind of contact lens. You may think this contact lens with circuits will be difficult to pop in and out, but it is wrong, please rest assured that it is very easy to pop in and out.
