Integrating AIoTs with Acoustic Levitation: Exploring Standing Waves and Oscillatory Dynamics of Small Objects
I. Abstract
The AIoTs Acoustic Levitation of a Small Object Experiment explores the principles of acoustic levitation using ultrasonic transducers to create standing waves that suspend small objects at pressure nodes. This experiment integrates the Internet of Things (IoT) with acoustic technologies to monitor and analyze levitation dynamics. Through precise control of ultrasonic frequencies (40 kHz) and transducer distance, polystyrene balls are levitated and their oscillatory motion under perturbation is recorded.
Advanced tools, including ImageJ and Python-based data fitting, are used to analyze the oscillation behavior and validate theoretical predictions. Students learn key concepts such as acoustic radiation pressure, standing wave formation, air resistance, and damping in oscillatory systems. The experiment also emphasizes real-time data collection via IoT platforms and Jupyter Notebook, offering a comprehensive understanding of acoustic levitation's applications in fields like materials handling, precision measurement, and microgravity simulations. This experiment provides hands-on experience in modern acoustic technology and data analysis, enhancing skills in both physics and IoT integration.
