Explore a groundbreaking webinar that introduces an innovative methodology for monitoring rodent physiology and behavior using guided ultrasonic waves technology. Learn how subtle forces generated by voluntary and involuntary muscle contractions in rodents create elastic waves that propagate through surfaces at ultrasonic frequencies, containing valuable information about the animal's physiological state, behavior patterns, and psychological condition. Discover the experimental setup utilizing an aluminum plate as a modified open field environment, where highly sensitive ultrasonic sensors detect guided ultrasonic waves (GUWs) including Lamb waves and shear horizontal waves generated by rodent movement and physiological functions. Understand the dispersive and multimodal properties of these waves that enable differentiation between physiological functions like heartbeat and breathing versus voluntary movements and behaviors. Examine how this non-invasive approach leverages structural dynamics, signal processing, and machine learning techniques to analyze free-moving rodents without traditional constraints or invasive monitoring methods. Gain insights into the interdisciplinary research methodology that applies acoustic emissions technology from aerospace and civil engineering to biological research, potentially revolutionizing how researchers study animal behavior and physiology in laboratory settings. The presentation covers the theoretical foundations of guided wave propagation, experimental protocols for data acquisition, and analytical methods for extracting meaningful behavioral and physiological information from ultrasonic wave patterns.
