Mohammed Islam, Professor of Electrical Engineering and Computer Science and Professor of Biomedical Engineering, College of Engineering, demonstrates use of a chemical sensor prototype in the EECS Building on North Campus of the University of Michigan in Ann Arbor, MI on December 8, 2017. The sensor is able to detect a variety of qualities from a distance of more than 100 feet away and could be used to identify traces of drugs and explosives, as well as speeding the analysis of certain medical samples. Previously such a sensor was only able to be used in closed proximity. Islam's research group built a laser-producing device that is able to send an infrared laser of various intensities through a series of different fibers that are connected.
