EoPlex Technologies, a Redwood City, Calif. company that sells miniature devices to generate and manage power for things like sensors and manufacturing processes, has raised $8 million in a third round of financing.

ATA Ventures led the financing with investments from existing investors, Draper Fisher Jurvetson, Labrador Ventures and Draper Richards.

From the company’s statement:

EoPlex produces components in layers using custom printing equipment and proprietary “inks” that carry ceramic, metallic or polymer materials to millions of locations. This allows the manufacture of components with integrated chambers, channels, sensors, circuits, reactors, energy scavengers, and other features. Many parts are created simultaneously in large panels and the only tooling required is low-cost printing masks. As a result, there is great flexibility to change designs quickly, allowing fast time to market and even modifications during full production runs.
