This study introduces a novel device for measuring electrocardiograms (ECG), bioelectrical impedance analysis (BIA), and galvanic skin response (GSR). The method successfully detects multiple bio-signals, demonstrating its potential for health monitoring.

Area of Science:

  • Biomedical Engineering
  • Physiological Measurement
  • Wearable Technology

Background:

  • Accurate and simultaneous measurement of multiple physiological signals is crucial for comprehensive health assessment.
  • Existing methods often face challenges with signal interference and require complex instrumentation.

Purpose of the Study:

  • To develop and validate a multi-modal bio-signal measuring device.
  • To enable simultaneous acquisition of ECG, BIA, and GSR signals with minimized interference.
  • To assess the feasibility of the implemented device for human bio-signal detection.

Main Methods:

  • Implementation of a device integrating ECG, 50KHz BIA, and 10-50Hz GSR measurement capabilities.
  • Utilized line filters, high impedance elements, and time-domain switching to separate and minimize interference between ECG, BIA, and GSR signals.
