Magnetic Paper Actuators

Electromagnet drawn on paper

A fun little project to try and make paper actuators.

This year I have design various kind of motors that are made from PCBs. These designs have inspired me to try and create an electromagnet drawn on paper! 

To draw the coil I have used conductive ink that created a much smaller resistance than if I used a normal 2B graphite pencil. I started out with 35 turns but the resistance still got to 2.4kohms, so i reduced the turns to 20 and got a 60 ohms independence. 

As shown in the video I managed to get some good results for attraction and repulsion. There is still some room for improving the "electromagnetic drawing". I can try to make the coils a little thicker to reduce the resistance as much as possible. I can also use thinner paper to get more flex and also try drawing it on both sides.

    This is my second attempt in trying to create Paper Electromagnetic Actuators! With the help of a plotter I was able to get much better results for the coils. There's a lot of applications these paper actuators can be used in but as a final demo I decided to make a paper butterfly that uses these coils to flap its wings.
