Abstract

This paper reviews the design and optimization of bioimpedance detection chips, focusing on the applicable scenarios of dual-electrode and quad-electrode and their trade-offs in measurement accuracy and portability. According to different detection requirements, the implementation principles and characteristics of ADC method, DAC method, successive approximation method, half-sine DAC method and baseline elimination technology are discussed in detail. Studies have shown that dual-electrode combined with efficient DAC method has significant advantages in portable devices, while the four-electrode configuration is suitable for high-precision impedance measurement scenarios. This paper provides theoretical support for the design of bioimpedance detection chips and looks forward to its application prospects in wearable medical devices and dynamic monitoring.

摘要

This paper explores advanced electrode modeling in the context of separate and parallel transcranial electrical stimulation (tES) and electroencephalography (EEG) measurements. We focus on boundary condition-based approaches that do not necessitate adding auxiliary elements, e.g., sponges, to the computational domain. In particular, we investigate the complete electrode model (CEM) which incorporates a detailed description of the skin-electrode interface including its contact surface, impedance, and normal current distribution. The CEM can be applied for both tES and EEG electrodes which are advantageous when a parallel system is used. In comparison to the CEM, we test two important reduced approaches: the gap model (GAP) and the point electrode model (PEM). We aim to find out the differences of these approaches for a realistic numerical setting based on the stimulation of the auditory cortex. The results obtained suggest, among other things, that GAP and GAP/PEM are sufficiently accurate for the practical application of tES and parallel tES/EEG, respectively. Differences between CEM and GAP were observed mainly in the skin compartment, where only CEM explains the heating effects characteristic to tES.
