Review of bioimpedance detection chip design
摘要
Abstract
This paper reviews the design and optimization of bioimpedance detection chips,focusing on the applicable scenarios of dual-e-lectrode 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.关键词
