Electrical Impedance Spectroscopy #7

Closed c-jw closed 9 months ago

This is a neat design, with a lot of hard work involved. Thank you for making and sharing this great piece of low-cost, portable technology.

I see that electrical impedance spectroscopy (EIS) is not built in to the software controls. Is there a hardware obstacle to achieving EIS with this design? Other obstacles? More generally, is this design capable of EIS?

Thank you!

In principle it could be programmed, but you would have to synthesize a sine wave digitally. I don't know how high in frequency this would work.
