Infrared Detector


Lehigh University has developed an Infrared (IR) sensor using ultrafast, un-cooled bolometer based on single wall carbon nanotube networks. This IR sensor offers lower intensity radiation and lower energy than current technologies. Assessments also suggest significantly better performance than that of conventional bolometers at a lower cost as well.

IR detectors are used in a wide variety of applications including law-enforcement, security, astronomy, life sciences, and gas detection. It is becoming the preferred method for toxic and combustible gas monitoring as well as for air quality management.[1] The growing number of applications, as well as the size of the global infrared sensor market (over $12 billion in 2009) indicates an open window of opportunity for this technology. Additionally, infrared telescope detector investment from funding organizations has been increasing, especially for those focused on gas detection. [2]

Lehigh University is interested in licensing this technology.  Lehigh would also be interested in finding a co-development partner.
