This headline is wrong. This has nothing to do with thermal cameras. It's "cloaking" by making it appear to have the same bulk thermal properties as it's surroundings.
The other caveat is that it only works if you're embedded inside a solid object. ;)
If you're in free space, the surface can't shine its IR differently in different directions, so under FLIR it will just look like the average ambient temperature. This is no better than existing (cheap and light) space blanket camo systems.
Well, could be still useful for hiding things in bulk materials ?
From scientific uses (sensors, cables or supports not disrupting experiments) to smuggling/hiding listening devices/trackers or boobytraps in bulk shipments, etc.
The main problem with space blankets is that they eventually heat up. So they only work for a little while, and then have to re-equilibrate back to ambient, then you put them back on, then take off to re-equilibrate...
So this new tech appears to overcome that shortcoming, for static objects.
More likely craft looking to reduce heat seeking missles or detection. Think better heat diffusion on helicopter or tank exhaust. Fixed installations would use thermal nets or space blankets.
There are loads of videos of Ukrainian FPV drones with thermal cameras hunting Russians trying to hide using something like space blankets. The blankets work up to a point, if the target were completely covered they would be hard to spot, but if parts of the soldier are not covered or are revealed during movement, it doesn't work out well for the target.
The videos remind me of the scene in Dune where Paul is hiding from the hunter-seeker that tracks based on movement.

I read the entire thing thinking it could cloak a soldier
We have AIs hacking people's computers and brains, and now we have the Major's thermo-optic camouflage. They were right to keep the newest Ghost in the Shell set in 2029-2030. Seems like it's right on time.
Interstellar space behaves as an almost perfect blackbody radiator, at a temperature of 2.725 Kelvin, due to the cosmic microwave background. As such, it does "emit heat", albeit an extremely small, but measurable amount.

Yes. Unfortunately many people are reading this thinking it's a FLIR invisibility cloak.
FYI Ukraine already has FLIR invisibility cloaks (fancy camo space blankets): https://www.youtube.com/watch?v=GfdF3iIwoX4
This is thermal cloak, explained here: https://www.youtube.com/watch?v=CM2RJi4mRZ0&t=52s
Notably it only works after the heat flow settles back down to equilibrium. If you're moving, it doesn't work.
Which seems like it would be good for fixed installations that need to remain undetected, no?

So a "heatpump cooling", store concentrated heat and inject it into the ground would work much better?

I'm not sure what you think the difference is?
This is gonna be going straight to Ukraine
I certainly hope so!

It could cloak a well insulated soldier from being a dark spot on the background.
I believe the Russians tried something similar in Ukraine with cloaking themselves to fool infrared drones.
Using 50 cent Mylar blankets which ... did not work like they hoped from the videos I've seen.
I mean, you're not gonna see the videos in which they did work.

Next cyberpunk wizpop toy: thermoptic cameoflage.
The future is turning out to be fascinating as concerning.
A Faraday for heat, eh?
I've always wanted to hide apples inside pears.
Does this work for things that emit heat?
Let me answer your question with a question: Does the infrared camera detect emitted heat?
Generally? Yes.
In this case? No idea.
Not clear where your question is coming from, but it detects heat that's emitted as infrared radiation.
Doesn't everything emit heat? :)
no, the vacuum of space does not emit heat
Interstellar space behaves as an almost perfect blackbody radiator, at a temperature of 2.725 Kelvin, due to the cosmic microwave background. As such, it does "emit heat", albeit an extremely small, but measurable amount.
The article mentions thats the next step
Maybe this could be used to hide a cold spot from a wafer bake pin.
Wow, a blanket!
More like an iron maiden
When you cover yourself with the blanket, others see the blanket. When you cover yourself with this, others see background.
