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.

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?

> Although the current cloak represents a major advance, the researchers want to develop more sophisticated versions capable of performing additional functions. One particularly important goal is to conceal objects that produce heat themselves
I read the entire thing thinking it could cloak a soldier

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.

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.

Next cyberpunk wizpop toy: thermoptic cameoflage.
The future is turning out to be fascinating as concerning.

Maybe this could be used to hide a cold spot from a wafer bake pin.

Let me answer your question with a question: Does the infrared camera detect emitted heat?
antonvs 2 hours ago
Not clear where your question is coming from, but it detects heat that's emitted as infrared radiation.

Generally? Yes.
In this case? No idea.

When you cover yourself with the blanket, others see the blanket. When you cover yourself with this, others see background.
