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?

Esteemed List Members,
I am working a problem where it would be helpful to define an ESD threat
level in a particular high humidity, metallic surroundings environment -
expectation is that ESD levels would be much lower than typical. I have a
very high level concept of how it might be done, some
