Digitally Controllable Multifrequency Impedance Emulator for Bioimpedance Hardware Validation
Original language description
The accurate emulation of the electrical impedance of biological tissues is crucial for the development and validation of bioimpedance measurement devices and algorithms. This paper describes a digitally controllable impedance emulator capable of reproducing values representative of tissue bioimpedance in user-specified resistance, reactance, and frequency ranges up to 1 MHz. The presented solution uses a 2R-1C impedance model to emulate the impedance characteristics of a biological tissue. Specific selection of each element value in this model is achieved using analog multiplexers with low R-on resistance. A MATLAB algorithm was developed for value estimation using target impedance requirements. An example design to emulate impedance from 1 kHz to 1 MHz with 10 Omega to 400 Omega resistance and -45 Omega maximum reactance is provided. The nonideal behavior of this design was evaluated and compared against experimentally collected impedance measurements. Deviations of 50 Omega up to 100 kHz (with approximately 5% deviations up to 1 MHz) and reactance deviations were also
