And infrared!
Point a remote control at your smartphone camera and check the viewfinder - you should be able to see the light!
Late last year, an app called GammaPix garnered some media attention as a kind of low-cost geiger counter. Now, a US test lab has confirmed that yes, smartphone cameras can detect radiation. The idea is simple enough: the CMOS cameras should generate some kind of signal in the presence of radiation, so all you need is an app …
I am suspicious of the FLIRONE why are there no pictures/videos on the site that illustrate what to expect?
Every video or picture on the website comes with the caveat "Thermal images shown are for illustration purposes only, and may not have been taken by the camera series depicted."
No a normal CCD with the IR filter removed can film near infra red, like the IR diode in your TV remote control but wont record thermal IR.
And yes im suspicious of the lack of actual images on the website, you can see actual imaging on various youtube videos such as this one:

But i do have a feeling there are some software shenanigans going on as the sensor is aparently 80x60 pixels, still quite impressive though.
Could work, you'd need a small reservoir containing odours in the form of tiny heat activated capsules and something like a thermal inkjet printer head to activate them.
I can envision cosmetics companies promoting this to sell their products...
Re. touch screens, magnetorheological fluids can be made transparent now and then addressed using a very simple coil printed onto a PCB under the screen so your phone could have a proper keypad.
