Power 3D

Printing also allows thicker, denser electrodes than conventional manufacturing, which the company says gives 80 to 100% higher energy density than incumbent cells.

Its cells target wearables such as smart rings, watches and earbuds, as well as body-worn medical devices and defense hardware. Cells can be as thin as 1.2 mm. Power 3D is based in Pittsburgh, Pennsylvania, and is affiliated with Carnegie Mellon University, where its co-founder Dr. Rahul Panat is a professor. It holds a granted patent and has National Science Foundation SBIR support.
