Some of you may be aware of the Flir One Pro that turns your smartphone into a thermal imaging camera.
This can easily be used irresponsibly:
If we can get you out the room in under 60 seconds (and) get your keyboard, I can figure out your password to your computer ... some devices are so strong that the thermal print can be detected more than a minute later and even have a way to detect the order in which numbers were typed. (source)
Just wondering if there is any effort in curbing this behavior by using low specific heat materials when making such keyboards. For example, keyboards made of a micro lattice structure like inflated foam or something that wicks heat rapidly.
