A team of researchers from Nanyang Technological University in Singapore has made a discovery that could revolutionize the use of contact lenses. They have created a miniature contact lens generator, just 0,5 millimeters thick. The unique feature of these lenses is that they can be powered using our own tears.
The lenses contain an enzyme called glucose oxidase, which generates electricity through a chemical reaction that occurs when it comes into contact with tear fluid. This power supply method is a safer alternative to those based on metals and other substances that are potentially harmful to the eyes.
It is important to note that this generator has only been tested on artificial eyes in the laboratory, but the results obtained so far are very promising.
The team managed to produce a current of 45 microamps and a maximum power of 201 microwatts, and the device can be recharged up to 200 times. Although these results are far from those obtained by classic lithium batteries, they are still very significant.
This technology could find application in a variety of fields, such as monitoring and diagnosis through contact lenses, as well as the use of smart lenses for recreational purposes.
While it may seem like an unnecessary solution for most people, the potential of this discovery is remarkable and could pave the way for important future developments.
