Abstract
In an embodiment, a system for wear monitoring, includes a wear surface, a metallic reflector embedded in the wear surface, a radio-wave transmitter, and a radio-wave receiver. The metallic reflector reflects radio waves transmitted by the radio-wave transmitter for detection by the radio wave receiver. Attenuation of the radio waves between transmission by the radio-wave transmitter and detection by the radio-wave receiver indicates a degree of wear of the wear surface.
