Which reacts with sodium and chloride ions found in tears to generate electricity. This enzymatic reaction is not only effective but also safe, avoiding the use of harmful metals that could pose a risk to the eye. The biocompatible nature of the materials used means that the battery can be integrated into the lens without causing irritation or adverse reactions.


Energy Efficiency and Longevity The battery's energy efficiency is impressive. It can produce a current of 45 microamperes and a maximum power output of 201 microwatts, which is enough to power basic functionalities in smart contact number data contact lenses. In laboratory tests using simulated tear solutions, it was found that the battery life can be extended by an additional hour for every twelve hours of wear. The battery can withstand up to 200 charge-discharge cycles, providing a reasonable lifespan for regular use.




Technical Details Advantages of friction-charged batteries Safety and Comfort One of the most significant advantages of tear-charge batteries is their safety and convenience. Traditional battery solutions for smart contact lenses often involve metal electrodes or induction coils, which can pose a risk to the wearer's eye health.
