Smart glasses developed that are powered by blinking
Engineers at Northwestern University have created smart glasses with health-monitoring functions that need no battery. They draw electricity from the wearer's blinking.
Engineers at Northwestern University have developed smart glasses that generate electricity from the wearer's eye blinks. The glasses include health-monitoring functions and do not need a battery at all. The development was reported by the news site Kursors.lv.
How it works
A person blinks on average 14 to 20 times a minute. Until now, each of those movements was simply wasted energy. The researchers' solution converts this mechanical motion into electricity, which powers the glasses themselves.
Why it matters
Smart devices usually rely on batteries that must be recharged or replaced. Here the energy source is the wearer, because the glasses run on an everyday movement that takes no effort. The source also notes that glasses are worn by a very large number of people worldwide, so such technology could be relevant to a wide audience.
The source text is truncated, so further details about the glasses and their health functions are not yet known.
