What factors do you think enabled Iddan‚ an engineer with no medical background‚ to pioneer the development of wireless endoscopy? Counterintuitive though it may seem‚ sometimes NOT being an expert in a particular field is conducive to creating breakthrough innovation in that field. Because Iddan was not a gastroenterologist‚ he was not “trapped” in the paradigm that the bowel must be scoped using a camera attached to a flexible rod (an endoscope). Instead‚ he applied concepts from his own background

Passive infrared sensor A passive infrared sensor (PIR Sensor) is an electronic sensor that measures infrared light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. Operating principle All objects with a temperature above absolute zero emit heat energy in the form of radiation. Usually this radiation is invisible to the human eye because it radiates at infrared wavelengths‚ but it can be detected by electronic devices designed for such a purpose
