Development of Simultaneous Sensor Location-Detection and Powering with Harmonic Radar Technology for Biomedical Sensing
This paper concerns the development of a biomedical sensing sensor which can be detected and powered by a harmonic radar. We propose some sensor component for the considering of sensing and charging simultaneously by detecting the second-harmonic signal strength. The sensor components are operated at 2.4-GHz band, including a compact dual-band antenna, a second-harmonic enhancement coupler, and a rectifier with a switched second-harmonic detection circuit. The maximum rectification efficiency is 57% when the RF switch off, and the difference of second-harmonic signal strength is 3.9 dB between switch on/off without the second-harmonic enhancement coupler when input power is 10 dBm. After adding the second-harmonic enhancement coupler, the maximum rectification efficiency is 45% with the RF switch off, and the difference of second-harmonic signal strength is 4.4 dB between switch on/off when input power is 10 dBm.
