Researchers have developed an automatic drawing machine that uses pens and pencils to draw metamaterials -- artificially engineered composite materials that derive their properties from patterned ...

• A flexible printed circuit is as much a mechanical device as it is an electrical device. • The neutral bend axis may not be in the exact middle of the material stack. • The reliability of flexible ...

Not all of us have CNC machines, laser cutters and 3D printers, and I’ll bet most of us didn’t start out that well equipped. The low-cost drawing machine that [jegatheesan] made for his daughter ...

WASHINGTON — Researchers have developed an automatic drawing machine that uses pens and pencils to draw metamaterials onto paper. They demonstrated the new approach by using it to make three ...
