Process relevant impedance measurement: Fast and robust

Abstract

Impedance measurement promises a fast and cheap method for characterization of virtually any matter. Especially for applications in medicine, biotechnology or food industry, bioimpedance measurement technique is believed to solve problems associated with established but time consuming and complicate methods. The practice, however, shows that despite of more than 60 years of intensive research in this field only a few applications are established. The success of impedance measurement relies more and more on the capabilities of devices designed for process environment. These devices have to be fast and robust and should be operable without trained technicians. In recent years an increasing number of solutions appear at the market establishing impedance measurement more and more as common tool in process control and quality management.
