Which Wire Mesh Specifications Influence Resistance and Heat Generation?

[algar32]

I am building a circuit that is hooked up to a 1.2v NiMH battery. I will be using a wire mesh similar to this: https://www.amazon.com/s/ref=sr_pg_...mesh&ie=UTF8&qid=1363133769&tag=pfamazon01-20

Unless there is a better mesh for this application.

I want as much power as possible to be dissipated as heat across this wire mesh? Can you help me find an approach to solving this?

Based off of reading the specifications here (and pasted below):

There are quite a few variables in the mesh specifications and I was hoping someone could help me determine which ones I can use to determine what mesh I should purchase.

Thanks.

Generally wire mesh operates at high current and batteries are low current.
Would it be possible to use standard resistors or nichrome wire?
If you would include details of what you are trying to do, someone might be able to help you.

I'm trying to make a heating mesh, similar to that of this mini vape device:

I just would like to know what mesh design specifications will result in the most heat. Thanks.

The easiest way to get the correct mesh is to ask http://www.instructables.com/id/The-Mini-Vape-Pictures/
However part #9319T188 at www.mcmaster.com is probably what is being used.

Thanks for the suggestion. In that article he actually says he uses: http://www.twpinc.com/wire-mesh/TWPCAT_10/p_325X325TL0014W48T

This seems to have quite similar specifications to the one you posted from mcmaster. I did notice mcmaster does allow you to purchase a small sample, which is a good thing if I end up purchasing from there.

My final question is this:
I know I can copy meshes from others projects, but is there any way for me to learn exactly which specifications of a wire mesh lead to a higher/lower resistance and create a higher/lower amount of heat? From prior research I have learned that a lower wire diameter means higher resistance (which makes sense), but how do the other specifications (i.e % open area, mesh opening size, thickness) affect the resistance of the wire mesh? Thanks.
