Drone-Enabled Non-Invasive Ultrasound Method for Rodent Deterrence (www.mdpi.com)

A novel drone-enabled system for rodent deterrence has been developed, utilizing a non-invasive ultrasound approach. The prototype features an eight-transducer spherical-cap ultrasonic loudspeaker array operating in the 20–70 kHz frequency range, paired with a custom PCB for signal generation and power amplification. This technology is notable for its potential to offer a sustainable crop protection method by eliminating the need for chemical deterrents. The effectiveness of the system has been validated through both laboratory and real-world field experiments, utilizing AI for rodent detection via thermal imaging. The significance of this development lies in its promise to enhance the efficiency of pest management in agriculture through UAVs. The use of a genetic algorithm for optimized drone flight paths and comprehensive testing phases provides a practical roadmap for transitioning this prototype into a commercially viable solution. Future work will focus on addressing limitations such as habituation effects in rodents and enhancing system robustness by integrating real-time adjustments based on AI detections. By exploring adaptive emission strategies and energy-aware path optimization, this initiative aims to revolutionize integrated pest management, making it more environmentally friendly and effective.
