How to build E-field sensor?
« on: January 08, 2020, 03:59:47 pm »
Hi!

I would like to experiment with generating extremely low-frequency E-Fields (1-10 Hz) by using some interdigitated electrodes. (IDE)
You know, those flat electrodes with the fingers and the spacings and whatnot.

I am looking to make fields in the range of 1 to 10 V/cm that extend .4 to 1 cm above/below the electrode.

How can I build/set up some equipment to create and test/verify these fields. I am not really familiar with doing this kind of electronics work.
Thanks for reading and any help.
EE and Tinkerer.
