Wearable Bioelectrical impedance monitor based on ADuCM350

Bioelectrical impedance analysis (BIA) technology is a non-invasive detection technology. In this paper we proposed a design scheme for a low power consumption, compact size and wearable BIA monitor. The monitor is based on a complete, small size, high precision meter integrated device-ADuCM350. The measured results are transmitted through the Bluetooth chip CC2540 to the e-watch. Dual power supply methods including solar cell and Li-MnO
₂
batteries are supported by the power management IC BQ25505.The proposed system has potential for monitoring the biological impedance of the human body in real time.
