Aside from weight, the Withings Body Scan WBS08 scale can also measure body composition, heart rate, and ECG. Measurements can be tracked using the Withings smartphone application. The most expensive part of this device is the Top Plate which is made of glass and includes ITO Electrodes.
WiFi and Bluetooth connectivity is supported by Synaptics SoC.
Analog Devices provided many ICs such as operational amplifiers and Bioimpedance Analog Front-End.
The MAX30009 is an integrated circuit designed for data acquisition system for respiration, Galvanic Skin Response (GSR), Electrodermal Activity (EDA), Bioimpedance Analysis/Spectroscopy (BIA/BIS), and Impedance Cardiography (ICG). In this solution this IC is used to evaluate Bioelectrical Impedance Analysis and Heart Rate Measurement.
