DIY Carbon Tape Heated Vest Modular System




About: DIY carbon heated clothing.
My main idea was to make a modular system that can be used with different clothes. I made two identical heating panels that can be combined into a single vest or attach to any outfit.

It is fully warmed up to 40 degrees in less than one minute.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Sewing

Each panel has 2 meters of carbon heated tape fron and now on Amazon. Chose the maximum width of the tape to provide a very even heating. Size panels 34 x 42 cm, since it is better suited for the size of my clothing.
In each panels tape connected in parallel 2x1m and has an independent power button.. It takes about 3A under 12V (36W) for each one or 72W together.

Step 2: "Soldering"

You can sew wire to carbon tape to make a good and flexible connection.  The contact place shouldn't be hotter than the tape itself. If not you must increase the contact area. Sewed contact very flexible.

Step 3: Connecting

Contacts may be sewed by sewing machine or just wraped with a wire.
But as you can see sewed contact is colder than the tape itself (left contact).
Wraped contact (on the right) is more hotter than tape.

Step 4: Using As a Modular System

On each panel sewn 4 pieces of Velcro . Now I can combine them into a single heated vest . A bit like a bulletproof vest:). It's very soft and thin.

Step 5: Using As a Modular System

Due to Velcro this vest will be comfortable to wear for a big man or a small woman.

Step 6: Using As a Heated Module

Each panel can be used independently with any clothes.
On the inner surface of conventional jackets I sewed 4 pieces of Velcro.
Now I can at any time fix the heating panel on a jacket and make it heated.

Step 7: And Yes, You Can Wash It!

Question 7 months ago

Hi, I definitely need to make myself something like this but was wondering what exactly you used to power each vest. I was worried it would be very heavy or expensive. Do you have an instructable that shows how you make the battery packs?! Also how long do they last and how heavy are they? Oh and can you / how do you recharge them?... Sorry for the barrage of questions!

Yes, it's a difficalt question for everyone including Tesla cars. A good heated vest/jacket should be 30 Watts of power at least. So you have to use a battery of 30W for 1 hour of using. That means 60W for 2 hours, 90W for 3h, 120W for 4h, etc. The best battery for DIY for now is Panasonic 18650 3400mAh. One battery weight is just 50g and it has about 10W of power. So you need 6 of them (total weight ~300g) for 2 hour.
Battery should be connected by protection board
This has charge function also.
Or you can buy a ready to use power bank 12v and at least 3a. Those are good enough:

Thanks for the reply Shenzhen, I don't know if I trust myself to make the battery packs myself without guidance so maybe ready-made power banks are the answer.

Hi Shenzhen,

Have studied your presentations with great interest but cannot fathom how to adopt it to my indestructible design.(heated face mask)due to my complete ignorance of current. Would appreciate it if you could take a look and give me some tips or ideas???

I am was delighted to find your DIY items. My partner and I have been designing and producing heated wear in NYC. We are interested in finding a manufacturer overseas to produce mass quantities for our line. Would you kindly advise us of any resources you recommend?

With great appreciation and respect,

How well would this work for heating a seat? I plan on using a seat from an electric grocery cart to make a tricycle and would like to heat the seat. I was thinking of gluing some padding to the seat, adding a layer of cloth, the adding the carbon fiber, then another layer of cloth. Would that be safe?

It's hightly recommended to use a silver glue to make a good contact. Please look at the photo.

Dang, I do not want 3A going anywhere close to my body, but I would love to make myself some heated socks this way! My toes are always chilly when I'm sitting at my computer, and 40-degree footsies sounds just divine... :-)

Hiya, 3 amps at 12 volts isn't going to do you any harm as an electrocution risk. Your skin's natural resistance won't let anything like that much current flow through you unless the voltage is much higher.

You can touch both poles of a 12v car battery at the same time without harm.

That said, don't stick the wires in your mouth, electrons at 12 volts are not grape flavour...
