Hi,
At first sorry if i am using not the correct terms but english is not my native language...

I think its something everyone knows...  especially when the air humidity is low you walk through your flat, touch something which is grounded and BAM, you got an electric shock.
Since a while i am having ths problem... but only at my desk.

I never get any shock when touching the water tap, doors, kitchen appliances...  never.
But when i sit down at my desk and touch my keyboard i get shocked.
Sometimes its that strong that my lighted keyboard goes off or the monitor blanks out for a few seconds.
Some day it will destroy my computer i guess   :scared:

So usually when i sit down i grab a metal paperclip or something and touch the ground of one of my socket outlets at the desk.
Then i can also see a spark but dont feel the shock.
After that everything is fine.

So i thought it would be good to get an ESD mat for my desk.
I put the mat on the desk under the keyboard and the mat is connected to ground.
Now i get a shock including spark when i touch the mat after sitting down.
I measured the resistance and from the mat to ground its only 100 Kilo Ohm.
So i guess the resistance should be higher ? The usual Adapter plugs i found online have 1 Mega Ohm, but the one which came with the mat has only 100k.
Would that help or would i still get a a shock ?

Btw, when i measure the resistance between ground and the keyboard its out of range.
The keyboard is obviously plastic and there is also no resistance measurable between any parts of the keyboard.
How can i get a shock when touching it ?

Any hint what i can do ?

Thanks!

Well, the obvious thing is to increase the humidity in the room during extremely dry weather. You could get a humidifier. Alternately if you have a stove or radiator or other heating hot spot, just set a pan of warm water there to evaporate and refill as required.

Walk around barefoot. I find that significantly helps on carpet.

It's probably your chair. The chairs we have at work (which we haven't used in ages due to covid work from home) would give me a shock every time I sit down or get up. I just got in the habit of touching the metal frame of the desk as I sit down or stand up. You can also get antistatic spray that you can spray on the carpet and furniture.

I relate this with the cloth softener used in the washing machine. I am sensitive to some chemicals and artificial smells and tend to use less softener.
But for some cloths made with a significant amount of synthetic fibre more is needed. Years ago a thought that antistatic component in softener is a myth up to the moment when I started to work in a lab that has proper ESD protection. I refused to use proper shoes and experienced ESDs proportional to the amount of softener used when I washed my cloth.
Now found one brand that is from natural components and I find it that is really efficient. My recommendation is to use more softener if your dress code includes synthetic materials.
