How do Combadges stick to uniforms? I never see what mechanism they use to keep them from falling off. I know behind the scenes they used magnets and Velcro. But for in-universe how do they stay on?
They attach to civilian clothing, and Geordi once stuck a combadge on a bomb, so I don't think it's something in the uniform.
"Geckos have the remarkable ability to run at any orientation on just about any smooth or rough, wet or dry, clean or dirty surface. The basis for geckos' adhesive properties is in the millions of micron-scale setae on each toe of the gecko form a self-cleaning dry adhesive. The tip of each seta consists of 100 to 1000 spatulae only 100 nanometers in diameter. Our interdisciplinary team of biologists and engineers has been working since 1998 developing models for how the natural nanostructures function in a hierachical combination of spatulae, spatular stalks, setal stalks, setal arrays, and toe mechanics, and developing nanofabrication processes which allow large arrays of hair patches to be economically fabricated."
Semi-interestingly on the subject of how a combadge is used, in the Shatner/Reeves-Stevens books they reference a few different ways to use them.
From memory the single tap obviously opens the channel as normal, holding fingers onto the surface forces an override (presumably if contact drops out due to a bad signal), I think two taps has the combadge begin recording and three taps triggers the playback.
I quite liked that.![]()

Artificial gravity is extremely reliable in Star Trek and apparently doesn't require much power, so it would be a good way to keep commbadges attached.
This, I guess...
