title: [A multichannel device for the noninvasive analysis of the state and function of organs and tissues].
abstract: The subject of this paper is to present a technical description of a high-performance, modular research device, designed and constructed with the aim of enabling the non-invasive investigation of the passive electrical properties of biological tissue in the frequency range 1 kHz-1 MHz. The modular hardware- and software of the device makes the system highly flexible when it comes to applying a wide range of methods for the non-invasive analysis of the state and function of biological tissues and evaluating them in a clinical setting. Furthermore, the concept also makes it possible to combine the modules in new ways for new applications, to accommodate future developments in bio-impedance research.
