Ninja Star Bio-Batteries!

ninja-star-battery-2

From Gizmag:

Researchers at the Binghamton University in New York developed their origami battery with a view to powering low-energy devices where electricity isn’t so readily available. Powered by the bacteria in a few drops of dirty water through the process of bacterial metabolism, the paper-based battery could be built to run a biosensor in the field at a cost of just five US cents.

Where the original design folded up like a matchbook with four modules laid on top of one another, the latest iteration packs eight batteries into a sliding, star-shaped frame. Within each of the modules are paper layers, an anode, proton exchange membrane and an air-cathode, while in the center is an inlet where the dirty water is fed.

As the battery is pulled apart into a donut-shape, fluidic pathways running through the paper layers carry the water into the eight fuel cells and kick off the electricity-producing chemical reaction. This state also allows the separate battery modules to connect with one another, which improves power output and also exposes the air-breathing cathodes to the air.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
