Conductive Cloth

[Mark]

Looking for conductive cloth.

Need small quantity.
Needs to be very flexible.
Needs to have a cloth i.e. non-conductive (cotton, poly etc) surface on
both sides.
Needs to shield against RF.

Where can I find it?

Tap Plastics stocks carbon fiber, but I don't think it is as suitable as
the cloth in the link above.

From vague memory, there is a medical product development company
owned by a French company that one time designed a flexible pullover
type shirt with inbedded conductors. They might pass on the name of
the company that made the prototype shirts.

Being an EMC Expert, I don't think you'll get the type of shielding
you want, you could try firms that make flexible EMC shielding, but
those products are pretty metallic.

There is a company that makes 'home' products, and from memory may
sell clothing specifically designed for shielding. Again from memory,
ELF shielding. I just did a search in my data base and since can't
remember their name, can't find it!

Let me know if you want their name, and I'll make an effort to knock
cobwebs off brain and find for you..

Small quantity = sample!

can be sure that someone like these will sell something:

Wow, an RF protecting hat, someone's making money from the tin foil
hat!
(I liked the pic of the office with RF protecting fabric... and all
the computer gear on the desk.)

Fun,

I wonder if the electrostatic jackets and lab coats would work?
Anyone know?

There is no electrical connection. It is to be used as a barrier
surrounding a sensitive device.

saran wrap

reynolds wrap

saran wrap

Available at your grocery store. You might also find something suitable
in a smaller quantity by ordering a hot sandwich (foil-paper composite
and add a napkin.) Depending how small a quantity you need, gum,
chocolate or cigarettes will also serve.

What frequency range ?

For low frequencies, it should look like a Faraday cage. This at least
requires some electric connections between the conductive surfaces in
the trousers and in the jacket.

Zippers are problematic, you may have to use some overlapping cloth
and metallic snap buttons to cover the zipper. Depending on frequency,
you may have to use metallic snap buttons at every 3 cm, making
dressing and undressing quite painful.

How about the head/face ? Is it covered or not ?

The largest risk for RF damage is the eyes, since there are no thermal
sensitive neurons in our eyes, so never look into a waveguide, which
might even theoretically be powered up.

The next sensitive part is our brain due to heat damage.

What is the point of protecting the body from RF exposure, if the head
is not protected ? If the head/face is not properly protected, any
microwave radiation will penetrate from the opening for the neck into
the lower body parts.

Not at all. Conductive hook and loop fastenings (Velcro (Tm)) are
available. Elastic conductive fabrics are available as well.

How about the head/face ? Is it covered or not ?

Conductive hat and veil, again with hook and loop fastenings.

Actually, protecting the feet and hands are the toughest problems.

Cute.



Speaking of plate armor, Boeing's "solution" to the 787 Dreamliner

burning battery problem is to fortify it inside 150 lbs of steel

casing.

So much for the weight advantages of LiIon. I wonder if it includes a

barbeque grill on top.

Wouldn't Space Shuttle tiles be a better solution for the Boing 787?
They are very lightweight, or so I understand, and were able to keep (most of) the shuttles from burning up on re-entry.

It would contain the heat well, perhaps too well. At 3" thick it has an
r-value around 1000 and weighs about 1 pound per square foot. It becomes
ablative around 1200 C.
