Why the study?
Classical ECG-derived respiration uses flexible electrodes at standard positions, prompting the introduction of an approach suitable for miniaturized sensors with low inter-electrode separation.
A miniaturized single-lead wireless sensor with optimized electrode positions can provide ECG-derived respiration estimates comparable to standard systems, enabling daily physiological monitoring.

A classical method for estimation of respiratory information from electrocardiogram (ECG), called ECG - derived respiration (EDR), is using flexible electrodes located at standard electrocardiography positions. This work introduces an alternative approach suitable for miniaturized sensors with low inter-electrode separation and electrodes fixed to the sensor encapsulation. Application of amplitude EDR algorithm on single-lead wireless sensor system with optimized electrode positions shows results comparable with standard robust systems. The modified method can be applied in daily physiological monitoring, in sleep studies or implemented in smart clothes when standard respiration techniques are not suitable.
