Abstract :
This paper presents a flexible non-intrusive power sensor tag with good proximity for accurate electric current and voltage sensing on a typical SPT-2 18AWG zip-cord power line of household appliances. The current and voltage sensors are simultaneously fabricated on a 100μm-thick flexible PET substrate. For the design of a 50-turns coil combing with two sensing electrodes in an area of 1.3×1 cm2, the sensor tag exhibits a sensitivity of 31.1μV/A and 98.9 mV/115 V for detecting 60Hz electric current and voltage, respectively.
