Just read about heart beat detectors in cars for intrusion detection and if someone is still in the car etc. Also seemed to be used by the military after searching the net after I read about it. But I couldn't find any info on how this works, does anyone know? Very curious. It seems to work through walls even. How??? Maybe the heart is doing a beat that has some kind of signature in a RF range? It seems to be easy to jam as there are jammers available for soldiers.
