Electrode Innovations: Self-Humidifying Electrodes for Long-Term HRV and ECG Measurements– José Näf (Pt3)

from Physical Activity Researcher · host paresearcher

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.   __________   This podcast episode is sponsored by Fibion Inc. | Better Sleep, Sedentary Behaviour and Physical Activity Research with Less Hassle --- Collect, store and manage SB and PA data easily and remotely - Discover ground-breaking Fibion SENS --- SB and PA measurements, analysis, and feedback made easy.  Learn more about Fibion Research --- Learn more about Fibion Sleep and Fibion Circadian Rhythm Solutions. --- Fibion Kids - Activity tracking designed for children. --- Collect self-report physical activity data easily and cost-effectively with Mimove. --- Explore our Wearables,  Experience sampling method (ESM), Sleep,  Heart rate variability (HRV), Sedentary Behavior and Physical Activity article collections for insights on related articles. --- Refer to our article "Physical Activity and Sedentary Behavior Measurements" for an exploration of active and sedentary lifestyle assessment methods. --- Learn about actigraphy in our guide: Exploring Actigraphy in Scientific Research: A Comprehensive Guide. --- Gain foundational ESM insights with "Introduction to Experience Sampling Method (ESM)" for a comprehensive overview. --- Explore accelerometer use in health research with our article "Measuring Physical Activity and Sedentary Behavior with Accelerometers ". --- For an introduction to the fundamental aspects of HRV, consider revisiting our Ultimate Guide to Heart Rate Variability. --- Follow the podcast on Twitter https://twitter.com/PA_Researcher Follow host Dr Olli Tikkanen on Twitter https://twitter.com/ollitikkanen Follow Fibion on Twitter https://twitter.com/fibion https://www.youtube.com/@PA_Researcher
