Crack Detection Using An Electromagnetic Sensor-Antenna For Structures

Currently problems on civil structures, terrestrial and aerial vehicle are the aging and fatigue, which generate cracks over time, bringing about risks and emergencies. To monitoring and detect cracks, frequently they are used devices like magnetics sensors, vacuum pneumatics monitoring, ultrasound, optics fiber sensors, and others, to verified structural health. Generally this devices use a larger space, have multiple connections, external or integrate power supply and a complex processing systems. So, this work proposes to design and implement a sensor-antenna at 2.45 GHz with supply wireless power energize, using microwave circuits and printed technology to improve simplicity and easy manufacturing, and without electrical connections to boost autonomy.
