Portable Bio-Signal Controller (Wearable)
A forearm armband that reads EMG or ECG signals and maps them to device or robot commands. I implemented basic filtering and envelope and threshold logic, with a desktop dashboard for live visualization and tuning. Bluetooth sends clean control events to downstream devices.
Technologies Used
The Problem
Hands-free device control with low cost and low latency.
What I Built
A forearm armband that reads EMG or ECG signals and maps them to discrete commands. A desktop dashboard shows live signals and lets me tune thresholds and filters in real time.
Tech Notes
Arduino Nano, EMG or ECG sensor boards, Bluetooth/BLE, basic filtering and envelope detection, Python dashboard with live plots. Safety and comfort considered for electrode placement.
Current Status
Demo controls LEDs and basic robot actions with low latency.
What's Next
Gesture classification with a small ML model, compact enclosure, better electrodes and strain relief.
