Abstract :
This paper presents a wirelessly powered strain telemeter for mechanical health monitoring applications. The telemter is integrated with a rectenna tuned at 2.4 GHz. The rectenna is comprised by a resonant printed dipole antenna, microstrip transmission line filters and commercially available high-frequency diodes. The experimental results demonstrate that the rectenna is able to deliver 8 mW of DC power to the wireless telemeter when illuminated by a 10-W Yagi transmitter with a gain of 15 dB placed at a distance of over 2.5 m.
