Researchers at the Nanyang Technological University (NTU) in Singapore have developed a groundbreaking battery that can power smart contact lenses and be charged with tears, according to a university press release.

Contact lenses have traditionally been used for vision correction, but with advancements in technology, companies have been working on creating smarter versions that can connect to devices like smartphones and display information directly to the wearer’s eyes. However, these applications require the lenses to have an internal battery.

In the past, companies have managed to incorporate augmented reality displays into smart contact lenses using thin batteries with induction coils and metal wires. However, these components pose risks to the user’s eyes.

Now, a research team led by Lee Seok Woo, an assistant professor at NTU’s School of Electrical and Electronic Engineering (EEE), has developed a battery that eliminates the need for metals. This micrometer-thin battery can be powered by tears, making it a safe and innovative solution for powering smart contact lenses.

This breakthrough could revolutionize the field of wearable technology, providing a more comfortable and safer option for users. The team at NTU Singapore is excited about the potential applications of this technology and is continuing their research to further enhance its capabilities.
