Frequency-Scanning Capaciflectors

Capacitive proximity sensors of this proposed type would be based on the capaciflector concept, with an extension of hardware and software designs to incorporate capabilities for scanning in frequency and analyzing the resulting capacitance-vs.-frequency data. The proposed frequency-scanning sensors would perform all the functions and offer all of the advantages of capaciflectors; in addition, they would provide information on materials within their capacitive-sensing ranges.
