Design Principles

"Embrace additive manufacturing for resource-efficient fabrication of advanced electronic components."

As designers and engineers push the boundaries of bioelectronics and flexible electronics, adopting additive manufacturing for OECTs can lead to more resource-efficient production processes. This approach minimizes material waste compared to traditional subtractive methods and opens possibilities for decentralized manufacturing, reducing transportation-related environmental impacts.

What This Means for Your Design

Using 3D printing and other 'additive' methods to make electronic parts like OECTs can be better for the environment because you only use the material you need, unlike older methods that cut away material. This can lead to greener electronics and new uses in areas like health sensors and brain-like computers.
