Static charge problem

This is a very serious problem for me now. I suffered for a long time but I couldn't find any answer to this problem yet.

I always have static charge. When I touch any metal things (door knob, my car or anything metal) it shocks me. Question : How can I get rid of this charge? I tried changing my shoes, my clothes etc. Didn't change. Is there any bracelet or any ring, jewelry which collects this charge on it? Please help.

Thanks

Re: Static charge problem

The static charge issue becomes worse in winter months as the air is more dry.

I usually try to touch something non-metallic before touching the metallic object.
This might partially discharge you before you touch the metallic object. I also have
found that if you keep your hands moist (using a hand moisturizer), the problem is reduced.

I guess you could also wear gloves -- but that might be awkward :D

Best regards,

Re: Static charge problem

Thanks for your advices.

If I generate this charge anyhow, this will discharge to somewhere in any way. Have you heard about magnetic bracelet? Does this help?

Static charge problem

Magnetic bracelets are junk. If you want to try to better dissipate an electric charge try using something like copper foil as a shoe liner and use a finishing nail or other conductive rod to go through the soul of the shoe, then on the bottom of the shoe try using something like metal thumb tacks (make sure you remove and enamal coating that may be on the thumb tacks) so that you have several metal points of contact with the ground to the coper foil inside the shoe. Even if you wear socks the natural amount of sweat on your feet will give you a decent level of conductance to the copper foil and hence to the local ground. Mind you this will do absolutely nothing (in fact it may shock you worse) if the object is what has the surface charge not you.

Keep in mind you are not generating this charge, you are mearly collecting it on your skin. The voltage required for a static arc would dissipate internally very quickly due to the high conductivity of human tissue/fluids so this is not possible.

Or buy shoes with leather soels or anti-static footware.

Carpets made of artifical fibre are often part of the problem. I used anti-static spray on the carpet around my workbench where I handle circuit boards.

Indoors a humidifier might help.

Re: Static charge problem

lkuzu,
I don't have an answer to your static build-up problem, but I can offer a trick that makes it less painful. When you discharge yourself but touching a metal object, do it through an intermediate metal object such as a key or a coin. You still get a discharge, but it doesn't hurt!

If you are assembling electronic equipment, and are concerned about damaging it, invest in an antistatic pad and an ESD wrist strap. Ozone gerators are also available, that ionize the air, making it conductive and incapable of holding a charge.
Regards,
Kral
