Far be it from me to introduce some additional scepticism, but that looks like an ordinary wrist strap, with standard push fit popper for connection to earth. If it was a wireless device surely it wouldn't need a connection point for a wire?
Based on the data from the website the wireless wrist strap is a fake device!!! Wow! can you give me companies who promote these kind of product in your area? Maybe they can provide us much more details on why they still sell this type of product that doesn't work.
We introduced wireless wrist straps here on a small scale for safety related jobs such as mass lead trimming. These straps operate by the "Corona" effect which, as it turns out amounts to this: You need to drink a case of that swill to convince yourself these straps really work. You can read up on the Corona effect and decide for yourself. Think about this - If this principle had any merit, Desco, 3M and the like would be offering them at exhorbinant prices.
We're pulling them from our floor and taking our chances with the hazardous operations or maybe going with ankle straps instead.
Seeing a product such as this and thinking about simple engineering. Every lightning rod I have ever seen on a building, home, tower, etc... had this long metal device called a "conductive wire" that runs into the ground.
I'll stick with the lightning rod approach. later marc
There are a number of sites dealing with the Corona Effect all with different slants in how it applies to them (Astonomers, physicists, Radio enthusiasts, etc.), but the basic definition I remember from my physics lessons at school is as follows:
The spontaneous dispersal of an accumulated electric charge. An example being lightning - the atmosphere becomes so charged that the air is ionised, providing a route to ground for the electricity to flow, and the charge to dissapate.
I'm guessing this is when dielectric breakdown of air occurs, but feel free to correct me if anyone knows better.
So, theoretically we could charge our operators up to a level where the corona effect would work, but they may not be too happy (or able)to carry on very productively.
