In this study, we developed a wearable device that enables minimally invasive monitoring of physiological parameters and behavior classification in freely moving rats. The device integrates a photoplethysmography sensor, a temperature sensor, and an accelerometer to measure heart rate, respiratory rate, oxygen saturation, body temperature, and physical activity. Furthermore, six types of behaviors were classified using machine learning based on accelerometer data. Simultaneous measurements with a commercial device and comparisons with visually assessed behaviors demonstrated high correlations and agreement, confirming the practical feasibility of the proposed system.
