A contact lens battery that charges as you cry has been developed!

Scientists have developed an ultra-thin and safe battery that charges with tears. This innovative technology not only meets the energy needs when using smart contact lenses, but can also be a promising solution for diabetic patients. Here are the details…

They will use tear-powered batteries for smart contact lenses

We have all seen it in the movies, especially in the Mission: Impossible series, the scenes where the main character provides information flow with a smart contact lens in his eye were unforgettable. However, such devices did not seem possible in the real world due to energy requirements. from Nanyang Technological University Lee Seok Woo and his team found a solution to change this situation, thanks to batteries that charge with tears.

This new battery technology is just a hair thick and small enough to be inserted into a contact lens. found in tears glucose, this allows the batteries to be charged. The moister your eyes are, the longer the battery life. And if you cry, think about the level the battery charge will reach. This technology can be used not only for smart contact lenses but also to measure the sugar levels of diabetic patients.

These batteries, which can be charged with tears, biocompatible salt water It works with the solution. This new method, which replaces traditional lithium-ion batteries, is designed for the safety of the user. Battery, both wired as well as chemical It can be charged using this method. The chemical method takes advantage of the reaction between the glucose on the battery and the sodium and chloride ions in the salt water solution. In this way, with an 8-hour charge, the battery reaches 80 percent charge level and provides several hours of use.

However, researchers are working to increase the voltage of the battery. Current prototypes produce a voltage of 0.3V to 0.6V, which data storage or Internet It is not sufficient for features such as connectivity. Still, this technology could have other uses, such as noninvasive glucose monitoring.

Currently, researchers are working to make these batteries suitable for commercial use and reduce their costs. Each battery costs just a few dollars It is designed to be. So, what do you think about this tear-powered battery? How can such innovations take place in our daily lives in the future? Don’t forget to share your comments with us!
