Breakfast Table Inspiration? 3D Printed Edible Electronics (Video)

When Professor Marc in het Panhuis was working on developing soft and edible materials for applications in soft robotics and bio-medicine, he only needed to look at his breakfast table for inspiration.

The iconic Australian Vegemite is ideal for 3D printing edible electronics. It contains water so it’s not a solid and can easily be extruded using a 3D printer. Also, it’s salty, so it conducts electricity.

In electronics, a breadboard is used to create and test circuits, so in this case, why not a real bread-board? Wholemeal, that is.

In this video, Prof. in het Panhuis 3D-prints his vegemite on the bread and completes the circuit, lighting up an LED.
