Technical Design & Hardware

Core Components: List the AD8232 module (for amplification/filtering), Arduino microcontroller (for sampling/digitization), and 3D-printed enclosure.  

System Architecture: Describe how the device captures 1-5mV signals through surface electrodes, amplifies them, and filters noise like 60Hz interference from power outlets.  

Safety Features: Highlight the "Isolation Barrier." Explain that the device is battery-powered to ensure users are completely separated from wall power, keeping leakage current below 10µA.  

Lead Configuration: While it measures three leads directly, it can mathematically reconstruct others for a six-lead system.
