Input impedance of the cochlea in cat
The Journal of the Acoustical Society of America, 1982Tones were delivered directly to the stapes in anesthetized cats after removal of the tympanic membrane, malleus, and incus. Measurements were made of the complex amplitudes of the sound pressure on the stapes PS, stapes velocity VS, and sound pressure in the vestibule PV.

Effect of External Source Impedance on the Input Impedance of Digital Impedance Circuits
2020 IEEE International Symposium on Circuits and Systems (ISCAS), 2020The input impedance of recently-introduced digital impedance circuits has been discovered to be dependent on the impedance of the external signal source. To address this problem, the theory for the dependence of digital impedance on external source resistance is presented.

Errors in the measurement of hydraulic input impedance
Journal of Biomechanics, 1970Abstract It is shown that significant erros may be made in obtaining the input impedance of an arterial bed when pressure and flow are not measured at the same site. These errors manifest themselves mainly in the phase of the input impedance. The sign of the phase errors depends on whether flow is measured proximal or distal to pressure.
