Scientists Invent Tiny Battery that Stores Energy from Human Tears to Power Smart Contact Lenses

Scientists in Singapore have made a super-thin battery, only a few micrometers thick. It can use tears to power smart contact lenses. These special lenses might show wearers information and messages without needing big gadgets.

The battery is safe for the body and uses a special coating to make electricity from stuff in tears. This discovery could change wearable tech a lot. It means we won’t need big chargers, and it’s good for the environment too. Smart wearable devices could become better and more practical because of this.
