@ Angillion
Q: "I'd like to know why a photograph of an imprint of an object on this gel is better than a photograph of the object."
A: Third dimension modeling; pictures tend to be flat

I'd like to know why a photograph of an imprint of an object on this gel is better than a photograph of the object. That applies to fingerprints or anything else.

@TwoTone I imagine it might could get finger prints without worrying about messin' them up. Also, a 3D fingerprint can provide much more information than 2D; a partial print could be more valuble with topographic data unique to an individual. (Unless I'm wrong or full of poo, neither of which would be an invalid description of most of the crap in my head.)

So basically, in theory, this can be used to get the imprint of, say an old 100 dollar bill (kind of just guessing it can do this considering what I saw in the video) and scan it into a computer and then use a 3D printer to make printing plates......all you would really need after that would be the ink.....just saying. This tech can be used for good as well as illegal things when combined with other tech.....in theory.

Angilion, if u can use to find glue droplets untampered on a post-it, ain't no chance of it corrupting fine detail. What about its potential in something like forensics?

The difference, is those high powered microscopes are expensive, big, and take effort to use. This is tiny, and incredibly simplistic.


This resolves to the same level as an optical microscope and a digital one with recording capabilities can feed straight to a computer.

Also, this gel just creates an imprint. To get it onto a computer you need...a digital optical microscope with recording capabilities (the camera shown in this video).

It's an impressive material, but I'm not convinced that it's hugely useful.

One advantage that a microscope with similar capabilities has over this gel is that you can record things without even touching them, let alone applying pressure to them. That could be very important in some situations.

Microscopes rely on things bouncing off a sample's surface, either photons for conventional microscopes or electrons for electron microscopes in order to gather and visualize data. Surfaces can vary from one to another and may require different settings to get a clear picture. The same known suface of the painted gel is used for all samples regardless of material. Microscopes also require small samples to fit within the constraints of the tool; additionally, electrom microscopes require a near perfect vacume which is not condusive to measuring living things. Gel can splt on just about anything. Finally, and most importantly, consider cost. Which is more expensive: An electron microscope found only in major universities and large R&D departments or a painted blob of rubber, a white LED light and a digital camera, even inlcuding special lenses? I'd be more comfortable trying the latter on new materials; also, you can't lug an electron microscope around on a reasonable expedition.

Hum... possible future almost-mechanical fingerprint recognition? I like!

how is this different from only using the camera being used?

Someone want to explain to me the difference between this and a microscope?
Looks really neat though.

Haha, I love it when they put the Gelsight on a camera. So they use a magnifying gel along with a magnifying camera to gain high resolution. Or, they could just use a magnifying camera...
