Preliminary study on parameterization of raw electrical bioimpedance data with 3 frequencies

open access: yesScientific Reports, 2022
This study tests the geometrical parameterization method for Electrical Bio-Impedance Spectroscopy (EBIS) readings previously proposed by one of the authors. This method uses the data of just three frequencies (therefore called 3P method).

Stochastic impedance [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2020
The concept of impedance, which characterises the current response to a periodical driving, is introduced in the context of stochastic transport. In particular, we calculate the impedance for an exactly solvable model, namely the stochastic transport of particles through a single-level quantum dot.
