Since sodium and chloride ions are additionally current in tears, these lenses might be virtually charged whereas carrying them.

As a result of the battery is so skinny, the most important query is how a lot energy it will probably retailer and the way lengthy it will probably final. The researchers used this on an eye fixed mannequin to check their invention.

Experiments confirmed that this battery can produce a present of 45 microamperes and a most energy of 201 microwatts. This quantity of power will likely be sufficient to run the machine for a lot of the day.
