BHO Anti-Static Wristband Eliminates The Need For A Ground Wire

By Luke Anderson

I remember the good old days of being a full-time networking/PC tech. I had my workbench where I did all of the major internal work on the computers that came in. I always had a couple of static wrist straps lying around (I had a tendency to wear them home and forget them), and I always hated using them. That stupid cord always got in the way of everything, though at least the ones I used let you remove the cord from the band, which was about as convenient as it got. Well now it seems that someone has created a static wrist strap that needs no grounding wire.

I’ll be the first to admit that I’m no electrical engineer, but I always thought that unless you had something to ground out the strap, it was pointless. This particular one appears to store and discharge the static using a small resistor and a screw. Here’s the full explanation given on the site (you’ll have to forgive the broken English, since it’s a Taiwanese site).

Principle :
As per physics principle of “Corona” Discharge effects and “Points Discharge”
by transmission of electric potential difference to arrive the effect of
electrostatic elimination?That is use the physical principle of “Engineering of
static” transmit is use ion push ion transmission pushing the static of human
body as per the way of high electric potential enter the activation area than
use ” Skin effect” pushing the static from activation area to the point of storing
static and between the storing static area with discharging have one meg ohm
resistor to stop the static return to transmit. Further, the device out side have
one screw, it connect with inside conductor circuit
(1). Use for – When people touch high Static power n careless make instant
large electrostatic charge conduction, can offer ion neutralization with outside
water molecule by the screw when the ion neutralize un-finish in time.
[It’s “Corona discharge effect ] to eliminate the static reach to the final
purpose of ” Static voltage balance”
(2). Can be use to make the function of electric potential zero
(Just use the rew touch the grounding source)
(3). Can be used to check the circuit termination.

If these work as described, I could certainly see a huge market for something like this, especially since it’s not nearly as ugly as the ones I’ve owned. The main problem you’re going to run into is actually getting your hands on one. They’re only about $11, but you’ll need to get it imported.
