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 come a long way in terms of technological advancements, with companies striving to create 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, Interesting Engineering has reported on how companies have incorporated augmented reality displays into smart contact lenses. These devices typically use thin batteries with induction coils and metal wires, which can pose risks to the user’s eyes. In response to this concern, 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 use of metals.

The newly devised battery is micrometer-thin and can be powered by tears, making it a safe and innovative solution for smart contact lenses. This breakthrough could potentially revolutionize the field of wearable technology and pave the way for more comfortable and efficient devices.

Professor Lee Seok Woo displayed the lens battery developed by his team, showcasing the incredible potential of this new technology. The NTU Singapore researchers have truly pushed the boundaries of what is possible in the world of smart contact lenses.
