Abstract:	This paper presents a flexible inductive coil tag for sensing the electric current in the two-wire power cords of household goods. The tag is fabricated using a complementary metal-oxide semiconductor compatible SU-8 flexible technology which provides unique device characteristics of low-cost, reliability and pervasiveness. With a 30-turns coil design in an area of 0.5x1 cm(2), the coil tag can provide sensitivity of 18 and 21 mu V/A for detecting 50-and 60-Hz electric current in the ampere regime, respectively.
