noncontact electrical impedance, mechanical scanning
We present a method for imaging based on noncontact electrical impedance measurements and mechanical scanning. Measurement results are shown for an initial system based on this concept. An impedance probe design is presented, applicable to the test system. Line-scan data plots of high impedance contrast structures show a good fit to a theoretical physical model. Image resolutions on the order of 100 m are indicated for the initial system. Two-dimensional impedance images of biological tissue generated by this technique are shown.
