Outline of Final Research Achievements

Monitoring of health conditions during bathing is important for prevention of such accidents as sudden malfunction of cardio- or cerebrovascular system and drowning. ECG and/or respiration monitoring in the bathtub was therefore proposed using bathtub-installed electrodes, indicating its medical availability . Such a system would provoke a feeling of strangeness and discomfort for a subject to see electrodes. To avoid such visible electrodes, capacitive coupling electrodes fixed outside the bathtub wall was newly devised, allowing cardiopulmonary monitoring in a fully non-conscious manner.
