Sofa electric shocks?

Our sofa invites us as static on whenever you touch a cell phone or laptop, you get a small bump, do you know that? (from the blow my laptop is already 2 times flooded)

Well, answer again? ) It was not me!

There are many factors that favor this electric charge (often when getting up from the sofa!). Especially synthetic material, there are quite "load happy". Do you know the crackle when you take off a sweater? Non-conductive substances rub together. So it is with your sofa: friction with synthetic fabrics!

Here are the essential factors:

Walk on socks or leather shoes / flaps instead of wearing rubber-soled shoes.
Wear cotton clothes instead of synthetic fabrics
Place a cotton rug in front of the sofa so that your feet can immediately divert the load.
Take a cotton blanket (or a bath towel for testing purposes) and place it on the sofa where you are sitting.
In dry air, often in winter, the effect is particularly strong. Humidifier can help. Because warm air is wetter than cold air and discharged the cargo better.
The load is particularly high when rubbing or slipping over the sofa with synthetic fabrics (sofa and pants).
Grab a larger metal object (such as a radiator or metal shelf) while standing up.

PS:

If you are charged, do not give anyone your smartphone, the spark that blows over can destroy the smartphone (there are several 1000 volts).

You can also "earth" on a larger metal body, with this tool: https://www.mindfactory.de/...27956.html

As you can see, this is not a joke but can be dangerous for your tablets or smartphones.
