Abstract

The number of drowning incident at home has been increasing steadily over time. The most common cause of the incidents is a situation that produces hemodynamic compromise during bathing. It can heighten the risk of causing a stroke, myocardial infarction, and loss of consciousness. This paper presents an inovative ultrasensitive vibration sensor for detecting viral sign that can measure micro vibration transmitted through a bathtub. Moreover, we propose a neuro-fuzzy system to extract hearbeat and estimate human states during bathing. In the experimental result, we discuss the effectiveness of the proposed system in terms of measuring precision, comparing with a pulse rate meter.
