Bioelectrical impedance spectroscopy is a widely used method for examining the properties of different biological structures, whether single cells, tissues or whole organ systems. All biological cells have electrical properties that enable to use impedance for describing changes in their composition and functioning.

Bioelectrical impedance is a standard technology used in different medical devices such as hemodynamic monitors and respiratory function analysers. Bioimpedance is increasingly used for characterizing tissues, both in vitro and in vivo, or counting cells, e.g. in haematology analysers or microfluidics.


  • Simultaneous 15-frequency measurement for detecting subtle changes
  • Real-time 1000 measurements per second sampling rate for monitoring rapid changes
  • Compact size suitable for embedding in OEM devices
  • Patented technology based on 40 years of experience in impedance measurement
  • Software enables simple customisation for any application

How our technology works?

The novel patented impedance spectroscopy technology enables to simultaneously measure 15 frequencies in 1ms. It is a cost effective yet highly versatile measurement platform for a wide range of applications in the medical domain. Quadra compact impedance-mapping technology can be used for creating portable connected devices or large-scale measurement systems.
