You know the conductive rubber used for electrical contacts? e.g. in LCD
display. It seems you need to deposit onto your material. I don't know how
they grow that. maybe just cut from bulk.

发帖数: 4 | 4 The rubber has some carbon in it. It's conductivity, it don't know. It should
be high as LCD don't need much current to drive. The simplest way to know is
to rip your waist watch open and measure it. The black soft stripe. And most
electronics which have touch pad have it, you phone, for example. I now
remember, I once measured one pad, it has resistance of order KOhm.

I have found that many people are using carbon black with some rubber (PDMS)
binder for this purpose. The conductivity certainly depends on CB content, and
good ink does need some formulation to improve the interface adhesion.
Actually, people have used this method for many years, think about your car
tires!
