Breakthrough in Wearable Technology: Tear-Chargeable Batteries for Smart Contact Lenses
In a scene reminiscent of a "Mission Impossible" movie, scientist Lee Seok Woo has made a significant stride by developing innovative batteries tailored for smart contact lenses. These batteries, with a mere 0.2 mm thickness, prioritize both safety and compactness, and are particularly vital for wearable technology such as smart contact lenses. Lee's inventive approach involves utilizing a biocompatible saline solution to charge the battery, whereby it reacts with a glucose coating to generate power. Remarkably, tears also possess the ability to charge the battery due to their glucose content. Although the current battery output hovers between 0.3V to 0.6V, Lee and his team at Nanyang Technological University are diligently working toward enhancing its capabilities. The potential applications of this breakthrough encompass healthcare, especially for diabetic individuals who require regular glucose level monitoring. Lee emphasizes the necessity of maintaining low battery costs to facilitate widespread adoption, aiming to make them affordable, possibly costing merely a few dollars once commercialized.
