Summary on Grant Application Form |
|
Surface acoustic waves are ripples that travel along the surface of a solid. A Love wave occurs when that solid has oscillations in the plane of the surface and the solid has a layer on top so that the wave becomes guided. As the surface of the solid (or layer) oscillates it is sensitive to any mass that attaches and, because the guiding layer keeps the wave at the surface, a Love wave is an extremely sensitive system. In liquids the oscillation entrains (drags) the liquid back and forth and the Love wave is then sensitive to both the viscosity and density of the liquid. Because A Love wave device can operate in liquids and detect mass attachment, it can be (and is) used as a biosensor. In this project it is suggested that a new class of Love wave is created when the solid is thinned and both the top and bottom surfaces become part of the oscillation, but the guiding layer on one surface continuing to enhance the sensitivity. The work will pattern the (polymer) guiding layer to create topographic reflectors and combine these with the interdigitated transducers to create acoustic mirrors. From acoustic mirrors acoustic resonant cavities and other acoustic structures used in telecommunications applications, but not so far in Love wave sensors, will be fabricated. Devices will be tested within our own laboratory and by biotechnologists.
