Portable 4 Wire Bioimpedance Meter with Bluetooth Link

To allow some clinical research based on bioimpedance measurements a small and easy to use device that can be used in the clinical environment is needed. A portable device for 4 wire bioimpedance monitoring is presented. It consists of a battery powered 100% autonomous device including Bluetooth capability. It complies with IEC60601-1 electrical safety and electromagnetic compatibility requirements. The device is able to measure impedances from 1 Ω to 1 MΩ within 100 Hz to 400 kHz frequency range with a maximum error of 3%. The accuracy of the device has been evaluated with dummy cells and the effects of the electrode impedance have been studied.
