Team Mosquito Portable Ultra-Sound Device for Mosquito Larvae Removal Spring 2026 – Current Project Description: Mosquitos are and continue to be the largest vector of human disease worldwide, placing vulnerable populations—especially those in under-resourced refugee camps at severe risk. An ultrasound transducer emitting sound at a frequency of 18-30 kHz has shown the ability to induce 100% mosquito larval mortality when deployed in small bodies of water. The development of an integrated ultrasound device to accommodate water sources within refugee camps can be advantageous not only for disease reduction but also for improving the sanitation of the often-limited water resources. Progress Update 1 Developed a prototype ultrasound driver circuit while troubleshooting output frequency performance. Created an Excel-based tool to organize components for achieving specific frequencies and built corresponding circuit models in Multisim. Conducted research on alternative transducer options, evaluated existing ultrasound driver circuit designs for prototyping, and investigated suitable electrical components to optimize system performance. Currently identifying and securing a reliable method to acquire transducers within the 18–30 kHz range to support ongoing prototype development and testing. Progress Update 2 Purchased a commercially available device, SIRENIX, and initiated preliminary testing at the Brackenridge field-lab. Currently coordinating with local vector control teams to develop a testing methodology and establish quantitative metrics for evaluating its effectiveness against local mosquito populations. Progress Update 3 An example circuit, adapted from Gadgetronicx, demonstrates how resistor and capacitor values can be adjusted to tune the circuit’s resonant frequency to match the operating frequency of the ultrasonic transducer.
