Electrode structure integrated into a belt for measuring a person's heart rate has a contact surface with neighboring wave fronts comprising troughs between the peaks

摘要

Electrode structure has a contact surface (20) with several neighboring wave fronts (R1 - R7) comprising troughs between the peaks. Preferred Features: One wave front consists of alternating peaks and troughs. The contact surface is made of electrically conducting material. The electrode is integrated into a belt.
