Linear PCB Motor vs Flexible PCB Actuator

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:

 4-Layer Linear PCB Motor2-Layer Flex PCB Actuator
Resistance32Ω23Ω
Maximum Temperature @ 5V51°C76°C
Power0.75W0.9W

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.
