Battery small enough to be injected, energetic enough to track salmon – Science Daily


Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon. The battery is just slightly larger than a long grain of rice, however is not the world’s smallest battery. Engineers have created batteries far tinier than the width of a human hair, but those smaller batteries don’t hold enough energy to power acoustic fish tags. The new battery is small enough to be injected into an organism and holds much more energy than similar-sized batteries.

  1. Apparently the full story says they were trialed on the Snake River last year, and the report of that is now available. Follow the story there. They implanted them in the salmon fry.

  2. Hey I could use a few of those too… Nice find and look forward to the tracking info down the road. Wonder which part of the Salmon gets the slightly larger than a long grain of rice battery?
