The electrical impedance of a material or device refers to the extent to which it opposes the flow of an electrical current. Impedance comprises inductance, capacitance and resistance, and is often represented as a complex value to allow for the inclusion of the phase between the testing voltage and measured current.
Impedance measurements represent a non-destructive way to probe the properties of a material or device by injecting a sinusoidal voltage and measuring the returning current with a phase-sensitive technique. When varying the signal frequency, impedance spectroscopy yields critical information about the frequency-dependent behavior of the sample and thus provides a fundamental characterization of its dielectric properties.
Whether you are characterizing a semiconductor junction with DLTS or developing a wearable biosensor, Zurich Instruments' products deliver accurate, fast measurements and give you access to an advanced toolset for data acquisition and analysis. Furthermore, our instruments cover the low frequency and high impedance range that is out of reach to traditional impedance analyzers.
