An electrical impedance tomography (EIT) SoC is proposed for the portable real-time lung ventilation monitoring system. The proposed SoC is integrated into belt-type EIT system with 32 electrodes and can show the dynamic images of the lung ventilation on the mobile devices. It has 3 key building blocks; 1) a T-switch for high off isolation > 60 dB between electrodes, 2) a I/Q signal generation...
A light-weighted body area network using 3-layer coin-sized fabric patches is proposed for sleep monitoring systems. It consists of two ICs, a network controller (NC) and a sensor node (SN), and also Wearable Band (W-Band) to connect them. The Continuous Data Transmission (CDT) protocol is proposed for low power and real-time scalability by in-order data transmission using W-Band among several sensors...
