Abstract

This study presents a novel dry electrode for reliable blood pressure (BP) monitoring, inspired by origami and the suction mechanism of leeches. A leech-inspired origami (LIO) sensor, incorporating a dry electrode and ECG sensor, was integrated into a sensing robot system. This system reliably measured ECG signals (signal-to-noise ratio of 21.7 ± 0.56 dB) and, paired with photoplethysmography (PPG), enabled accurate BP monitoring (average systolic BP difference of 0.03 mmHg compared to a sphygmomanometer). The LIO system facilitates the development of feasible BP sensing tools for remote healthcare monitoring.
