A 1.4m Omega-Sensitivity 94db-Dynamic-Range Electrical Impedance Tomography Soc And 48-Channel Hub Soc For 3d Lung Ventilation Monitoring System

A wearable electrical impedance tomography (EIT) system is proposed for the portable real-time 3-D lung ventilation monitoring. It consists of two types of SoCs, active electrode (AE)-SoC and Hub-SoC, mounted on wearable belts. The 48-channel AE-SoCs are integrated on flexible printed circuit board belt, and Hub-SoC is integrated in the hub module which performs data gathering and wireless communi...
