You can charge someone up and discharge them into an ESD target. I did this
with myself (I don't like going above 10 kV) to develop a better model. A
person does not appear as a simple capa

Human. But I am wondering if I could simulate a human with some kind of
"machine" for the purpose of defining a human ESD threat.

Ken,
Do you mean human ESD or machine?

After looking at the triboelectric series, it seems that the only time a human
would charge negatively is after falling off an airplane! Otherwise, you are
likely to be positevily charged.

That makes sense, but it only addresses half of the ESD environment question,
which is how high a potential can something be
resistor,
but in terms of modeling scuffing one's feet and measuring the resultant
charge collection?

RE:

eee.
Simple thing to do is take an ESD simulator and try charging some objects in
that environment and see if they will hold a charge In high humidity, I'd
expect charges to bleed off very quickly on most objects, which is why the ESD
threat would be low
In low humidity, of course, the charged
