Before I can start building robots with this thing, I need to measure its characteristics and test its limitations.

In this video, I have tested my Flexible PCB actuator and also compared it to my Linear PCB Motor which has the same dimensions but different layer count. The measured data is shown bellow:

The flex PCB has half the turns, so its resistance is lower. This means that more current can pass through it, so obviously it gets a little hotter. This means that this flexible pcb actuator can be used with lower voltages. The thin dielectric of this pcb also improves the coupling of the magnetic field.

I was also able to reach a maximum operating frequency of 65Hz.
