Novel on-body microwave antenna array testbed for highly-sensitive measurements of wrist bone signature

Osteoporosis represents a major health problem, resulting in substantial increases in national health care costs. Current methods to detect osteoporosis rely upon ionizing techniques such as Dual-energy X-ray Absorptiometry (DXA) and Quantitative Computed Tomography (QCT). The objective of this work is to create and validate a low-cost non-ionizing method, which uses modern RFID technology, and to construct the corresponding testbed.
