Impedance planimetry: a new approach to biomechanical intestinal wall properties.
This paper surveys impedance planimetry, a technique based on the measurement of electrical impedance for estimation of active and passive biomechanical wall properties of the intact intestine. The paper mainly concerns methodological aspects of the recording technique and possible sources of error. Furthermore, the historical background concerning developments of the technique and physiological results during the last two decades are described.
