impedantiespectrum
The impedance spectrum refers to the relationship between impedance and frequency in electrical and electronic systems, particularly in materials and components exhibiting frequency-dependent behavior. Impedance, denoted as Z, is a complex quantity that combines resistance (R) and reactance (X), representing the opposition a circuit or material offers to alternating current (AC). It is expressed in ohms (Ω) and varies with frequency, providing insights into the dynamic properties of systems such as batteries, capacitors, resistors, or biological tissues.
In practical applications, the impedance spectrum is often visualized as a plot of impedance magnitude or phase
The measurement of impedance spectra typically involves applying a small AC signal over a range of frequencies
Applications extend beyond electrochemistry to fields such as materials science, biomedical engineering, and acoustics. For instance,
