Reducing electrical output of keyboard?

I have a wired laptop with ethernet connection,  with a separate keyboard connected by USB port. Is it possible to reduce the keyboard's strong electrical field in any way? Using a grounding sheet but it makes no difference. Sorry if I sound thick but am new to this!

I'm extremely EMF-sensitive, I don't notice any effects from a K400-series Logitech keyboard. It doesn't have a cord that carries power, just a couple batteries, and relies on very intermittent communication with the computer.  Best of all I can use it from 10-40 feet away.

Thanks David I just checked Amazon and they're available there. Its comforting to know others are extremely emf sensitive too.
I used to be able to travel in the back of a car down a highway with a blocsilver canopy over me and protective clothing on, but now with the amount of modern electric cars and all their computery onboard even that is proving almost impossible. I have decided the only way is to go out either very early or stick to remote roads. How do other people cope with travelling?

Some people apply shielding tint to their car windows. Try searching this forum for window tint.
