John and Derek talk to Dr. Jacob Fraden of Sensor Jacket about augmenting the capabilities of smartphones by adding additional sensors to the case to do all kinds of interesting stuff like take surface temperatures, analyze breath, check the thermal distribution of heat in a building, stud detectors for construction workers, all kinds of stuff. The various sensor jackets would essentially turn a smart phone into the next best thing to a Star Trek tricorder.
