Smart contact lenses look to upgrade our wearable technology

Scientists have developed a smart contact lens with a rechargeable supercapacitor power source that can be charged up wirelessly. It could be used to track a wearer’s health by monitoring fluid in the eye for biomarkers linked to diseases such as diabetes. These lenses might even usher in a new era of augmented reality, taking wearable tech to a new level.

The smart lens contains a tiny supercapacitor alongside a power unit. These are printed on the lens outside of the area that covers the wearer’s pupil, meaning it won’t interfere with their vision.

Use the starter slide with your class to help them link their understanding of electrical conductivity with nanoscale electronics.
