The purpose of this study is to monitor the autonomic nervous system with average skin temperature and its variability, of which both are compared with heart rate variability. Six healthy male college students participated in a test which is composed of rest for 5 min., exercise for 20 min. and recovery for 10 min. to measure their ECG and skin temperature with BIOPACK. The test found similarity between...
A new flexible, dry electrode is examined for recording surface electromyographic signals and compared to a conventional Ag/AgCl electrode. A suitable dry electrode would enable practical implementation of wearable mobility monitoring systems. Results from a preliminary experiment are presented in this paper. Measurements were performed on the right tibialis anterior during a series of small and large...
An approach is proposed for detecting heart rate for controlling electrically assisted bicycle. This method is based on capacitive coupling involving the electrode, the cloth and the skin. A proposed system was fabricated to explore the feasibility of the approach and evolution experiments were conducted for 4 men. Validation of the system revealed the following: (1) ECG signal was successfully obtained...
Laser Doppler vibrometry has been recently applied for non-contact monitoring of the cardiac activity, both in terms of cardiac rate and heart rate variability, measuring the velocity of the skin surface of the chest wall and the neck (optical vibrocardiography, VCG). To go further insight in the analysis of VCG recordings, in this study authors have compared heart sounds by digital phonocardiography...
The effectiveness of electrocardiogram (ECG) monitors can be significantly impaired by motion artifacts which can cause misdiagnoses, lead to inappropriate treatment decisions, and trigger false alarms. Skin stretch associated with patient motion is a significant source of motion artifacts in current ECG monitoring. In this study, motion artifacts are adaptively filtered by using skin strain as the...

Wearable electronics may become a key element in the future to measure a patient's physiological parameters not only in a clinical environment. This work describes dry electrodes based on conductive rubber, which can be integrated into clothing for monitoring purposes. Characteristic electrical properties like warm up time, skin-electrode impedance and motion artefacts will be discussed.
