Abstract
The micro whistles have been fabricated by ultrasonic hot embossing of thermoplastic foils at low-cost and their overall size is approximately 1Â cm. The paper also describes how to overcome obstacles such as accidentally generated ultrasonic noise, frequency shifts due to changing activation forces of the whistles, and distinguishing the signals of different whistles.
