Electric Impedance of Piezoelectric Ceramics under Acoustic Loads
ECTI Transactions, 2014 The electric impedance of piezoelectric ceramics is influenced by variations in the acoustic load. This situation is very common for ultrasonic applications in medicine where the irradiated media can present different interfaces and impedances to the ...

Multiscale electrical impedance tomography [PDF]
Journal of Geophysical Research: Solid Earth, 2003 Electrical impedance tomography aims to recover the electrical conductivity underground from surface and/or borehole apparent resistivity measurements. This is a highly nonlinear inverse problem, and linearized inverse methods are likely to produce solutions corresponding to local minima of the misfit function to minimize.
