The device utilizes advanced piezoelectric transducers to emit targeted high-frequency sound waves. These silent ultrasonic emissions mimic biological cues—such as the sound of male mosquitoes or natural predators—that female mosquitoes naturally avoid. Because the frequency is far beyond the range of human hearing, the wristband offers unobtrusive, 360-degree personal protection without pungent smells, greasy residues, or toxic pesticides.
