EEVblog 1567 - Wireless ESD Monitor? - The IONA StatIQ Band TESTED

[EEVblog]

Does the $1200 IONA Tech StatIQ wireless ESD monitor actually work? or is it just BS?
And if so, how does it work?

Market it to Ghost hunters and Prana healers and retire early.

It could also be sold as a scifi prop, the spinning gold part is just wild.

Indeed!
If I had done a modicum of reserach I would have found out it's a minature Field Mill.

Basically a classic field mill. I've been building field mills for some years now.
The reason why it's gold plated actually is not corrosion, as you might suspect.
 It  is because gold (1,69V) is galvanically closest to oxygen (1,76V).
So that increases the accuracy of your field mill.

If designed correctly, field mills can be pretty accurate.
The challenge when designing a field mill is having an instrumentation amplifier with extremely high CMRR, as jt will pick up all the 50Hz noise around you from the power lines.

And then Medhi uses the same device to prove why living or existing near high-tension power lines makes you tingle but doesn't cause cancer! Lol

Tho, I really wish I was near that bridge to experience this myself! The closest I've been to this type of thing is the Hoover Dam and it wasn't nearly as dramatic because of the EXTENSIVE grounding plane they established around the visitor facilities near the power lines leaving the power plant! I mean, 000 gauge wires bolted to the rocks running in an extensive array around the parking garage, and even the hand railing on the steps was ground strapped - taking no chances! Lol



P.S. - If no one beats me back there, I'll grab some pics of this all if anyone is interested the next time I'm through there sometime between now and fall 2025.

Apparently, if you stick fluorescent tubes into the ground under high-voltage power lines, they will glow a bit.
