Multi-Parameter Chipless RFID Sensing Tags Utilizing Additive Manufacturing
Nondestructive evaluation (NDE) plays a critical role in monitoring and maintaining our space and aerospace infrastructure. Wireless passive sensors are of especially high interest and value for these application areas due to not requiring a power source, having a small form-factor, and being minimally invasive to structures. This work aims to enhance these advantageous features by beginning the development of tunable multi-parameter wireless, passive, microwave sensors for simultaneously monitoring at least two parameters, such as temperature, pressure, humidity, and strain, which will provide more integrated sensing capabilities in a smaller package. These sensors can be classified as chipless RFID tags, which have been the focus of my graduate research for the past four years. By building on my past works on chipless RFID, continuing to work with Dr. Reza Zoughi at the Center for Nondestructive Evaluation, and harnessing the power of additive manufacturing, environmentally sensitive substrates that can be customized for specific dynamic range and sensing resolution needs will be created.
