Experimental ECG Electrode-to-Chest Strap Connector
In most setups, ECG units rely on disposable stick-on electrodes placed directly on the skin. These provide good signal quality but can be cumbersome to attach and replace, especially for repeated measurements.
As an experiment, we explored a simple workaround: sticking two ECG electrodes together to create a “male-to-male” style connector. This allows the ECG unit to interface directly with a standard heart rate chest strap, making the connection more convenient and reusable.
Signal Quality
Despite the unorthodox approach, the resulting plots showed a discernible ECG signal. While this setup is unconventional, the clean waveforms suggest that it may be a viable way to capture ECG data in a more user-friendly format.
Electrode Longevity
he example shown here was recorded 30 days after the electrodes were initially stuck together. The fact that the connection remained intact and functional suggests some degree of longevity, though this is likely to vary depending on the type and brand of electrode used.
Key Takeaways
- Simplified connection: No need for repeated stick-on electrode placement — just connect to the chest strap.
- Good signal quality: Comparable to standard electrode setups in this experimental test.
- Potential for reuse: At least one month of functionality was observed, though results may vary.
This is still experimental work, but it highlights an interesting way to rethink how ECG units might connect to wearable systems. Feel free to drop a comment below
