Comparison of Active Electrode Materials for Non-Contact ECG Measurement

A Non-contact Electrode for Measurement of Electrocardiography

A Hygroscopic Sensor Electrode for Fast Stabilized Non-Contact ECG Signal Acquisition

A capacitive electrocardiography (cECG) technique using a non-invasive ECG measuring technology that does not require direct contact between the sensor and the skin has attracted much interest. The system encounters several challenges when the sensor electrode and subject's skin are weakly coupled. Because there is no direct physical contact between the subject and any grounding point, there is...

Active Measurement of Contact Sounds

We describe a novel system for robotic measurement of contact sounds. This system is well suited for acquiring impulse-response sound models. A brief explanation of the sound models is included. We also describe experimental results to illustrate the process of acquiring sound models using our system, and a brief analysis of the results. The initial results are promising and could lead to appli...

Design of a Non-intrusive 2-lead ECG System Using the Active Insulated Electrode

For patients at risk of developing cardiovascular complications, it is important to monitor their heart signal to ensure proper functioning of their heart and a natural, healthy cardiac cycle. Preferably, this monitoring should be done on a continuous and long-term basis. Both of these objectives can be achieved using the electrocardiogram. While the traditional 12-lead ECG is currently used in...

Relative Measurement of Differential Electrode Impedance for Contact Monitoring in a Biopotential Amplifier 601 Relative Measurement of Differential Electrode Impedance for Contact Monitoring in a Biopotential Amplifier

In this paper, we propose a simple and relative electrode contact monitoring method. By exploiting the power line interference, which is regarded as one of the worst noise sources for bio-potential measurement, the relative difference in electrode impedance can be measured without a current or voltage source. Substantial benefits, including no extra circuit components, no degradation of the bod...
