From Insect Wings to Miniature Loudspeakers - A Bionic Modelling Approach

Project description

Bioinspired miniature loudspeakers

Crickets and bush-crickets produce courtship songs to attract distant mating partners by rubbing their wings together. These songs are highly varied in pattern and pitch, specific to each species and are often surprisingly loud, considering the small size of the insects producing them. An explanation for the high amplitude of songs lies in the special structures of the wings themselves as they have evolved to function as resonators for their own song, comparable to the resonating body of a violin or guitar. Taking a leaf from nature’s book, InWingSpeak is planning to study the song-producing wings of various cricket and bush-cricket species to lay the foundations for development of biomimetic resonators and transducers. Using state-of-the-art experimental and mathematical methods, researchers plan to unravel the intricate relationship between wing morphology and sound production. 3D-modelling and in silico simulation of a wing's evolution toward optimised sound production will provide invaluable insight to engineers interested in creating or optimising miniature loudspeakers for biomedical devices like hearing aids.
