IMPEDANCE ANALYZER FOR LOCAL MEASUREMENTS OF ELECTRICAL CONDUCTIVITY IN BIOLOGICAL OBJECTS

Tomasz Grysiński, Zbigniew Moroń

Abstract

The subject of the publication is a portable device for measurements of impedance magnitude in the range of 25 Ω ÷ 2.5 kΩ, with the phase angle of -90 ÷ 0°, within the frequency band of 100 Hz ÷ 100 kHz. Small measuring current, 10 ÷ 100 µA, allows for the use of miniature sensors for the measurement of sample with volume as small as several mm³. The device was designed specifically for local measurements of electrical conductivity in biological objects.
