Abstract

Presented is an active electrode design for electrical impedance tomography spectroscopy (EITS) which contains both current stimulation and sensing pathways, and also enables the simultaneous measurement of bio-potential signals (EEG/ECG). The entire circuit is manufactured on a small circular FR4 PCB with the bottom layer forming the electrode plate. A custom sealed plastic enclosure was designed and forms a classical cup-shaped scalp electrode to hold the conductive paste. The proposed design is of low power, drawing 8 mW when powered at 5 V, and provides a large bandwidth (20 MHz). It has a large input impedance (>1010Ω 5 pF) and is low noise (10 kHz). Performance was evaluated using a bench test (EIT image phantom) and in vivo recordings (EEG).
