  • DEVICE FOR DETECTING INTERACTION WITH AN OBJECT
    Publication number: 20110095651
    Abstract: A device and method for the detection of the interaction between two or more objects is disclosed. The device utilizes electrical impedance spectra measured from a piezoelectric element attached to one such object. Comparison of such spectra along a range of traverse allows precise estimates of distance to be made. One useful application is the topographical mapping of a surface.
