My hope is to explore [the existence of] dynamic correlation of plant tissue (leaves to start with) electrical resistance to stimuli. I've heretofore conducted experimentation reasonably sure enough of the techniques and materials I'll need that I've never posted for such advice in a public forum. So this is my first post to do so. I foresee a signal-to-noise challenge with the resistance measurements that I'd just as soon enlist help with. Has anyone had a problem getting good readings in light of this? Or is my concern too much ado about nothing? Any advice from experience as to the proper: - equipment? - materials? - technique? Do you have links to previous work of this type? How did they make electrical contact with the plant leaves? Do you just use the same contact pads as for an EEG or EKG? (Thank you, berkeman) Thank you!!
