Can electrode systems self-regulate moisture to keep data quality high for 10 days? José Näf explains how Nahtlos’ innovative design improves both signal stability and skin comfort in long-term ECG and HRV tracking.
In this third episode, Dr. Olli Tikkanen continues the deep dive with José Näf into how advanced electrode technology is addressing the long-standing issues in long-term heart rate variability and ECG measurement. José introduces Nahtlos' breakthrough: a hybrid electrode with a water reservoir and a semi-permeable membrane that mimics natural sweating, maintaining low impedance and high-quality signals for up to 10 days.
They also explore how breathable adhesives, biocompatible conductive textiles, and precise material selection reduce skin irritation and improve patient comfort. José shares the testing process, from self-experimentation to hospital trials, and how their team developed their own standards for evaluating signal quality. This episode gives a rare behind-the-scenes look at how wearable ECG technology evolves from lab innovation to clinical use.
