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

Contact lenses have long been used for vision correction, but with advancements in technology, companies have been striving to create smarter versions that can connect to devices like smartphones and display information close to the wearer’s eyes. To achieve this, the lenses require an internal battery.

In the past, Interesting Engineering has highlighted how companies have successfully incorporated augmented reality displays into smart contact lenses. However, these devices typically use thin batteries with induction coils and wires made of metals, which pose potential risks to the user’s eyes.

Now, a research team led by Assistant Professor Lee Seok Woo from NTU’s School of Electrical and Electronic Engineering (EEE) has developed a battery that eliminates the use of metals. This breakthrough battery is incredibly thin, measuring only a few micrometers, and can be powered by tears.

The team’s innovative approach not only ensures the safety of the user’s eyes but also opens up new possibilities for the future of smart contact lenses. With this new battery technology, users can enjoy the benefits of smart contact lenses without compromising their eye health.

The development of this micrometer-thin battery marks a significant step forward in wearable technology and brings us closer to a future where smart contact lenses are seamlessly integrated into our daily lives. The research conducted by NTU’s team showcases the university’s commitment to pushing boundaries and driving innovation in various fields.
