Human Body Odor Visualization with 2-Dimensional Sensing

Odor space shapes or images that visualize spatial chemical information are new information that could not be used so far, and have wide application fields that use volatile chemical substances as information. Search for a person at the disaster sites, search for odor marks in forensic investigation, biometrics, medical diagnosis, environmental pollution sources and illegal drugs, dangerous goods detection, fire detection, and agriculture. In this paper, trials on odor imaging with newly developed opto-chemical sensor films with 2-dimensional geometry are described. The 2- dimensional chemical sensor has high potential for providing rich information about chemical substances based on extremely high-density chemical sensor fabricated on the film.
