Abstract
A smart structure comprising a rotatable shaft, and a sensor integrated with the shaft, a resonant detector circuit integrated with the structure for detecting a sensor output, and an external exciter circuit; the detector circuit having first coil means and the exciter circuit having second coil means magnetically coupled to the first coil means when aligned across a gap; and control means exterior the shaft for producing an output that corresponds to the sensor output compensated for the gap.
