Abstract

This research proposes use of Fiber Bragg Grating (FBG) sensors to measure and monitor patient body temperature non-intrusively on a Smart Bed Sheet. The use of FBG sensors allows smart bed sheet to have the look and feel of an ordinary conventional bed sheet since FBG sensors have a very thin and light linear geometry. Additionally, they are dielectric in nature, and have a total immunity to electromagnetic and RF interferences. Recent developments in FBG research have made these sensors considerably inexpensive but very reliable. Simple signal processing techniques can extract very precise temperature from FBG sensors.
