Discover Open Access research at Strathprints

It's International Open Access Week, 24-30 October 2016. This year's theme is "Open in Action" and is all about taking meaningful steps towards opening up research and scholarship. The Strathprints institutional repository is a digital archive of University of Strathclyde research outputs. Explore recent world leading Open Access research content by University of Strathclyde researchers and see how Strathclyde researchers are committing to putting "Open in Action".

Micromachined unimorphs and bimorphs

Farlow, R. and Galbraith, W. and Kelly, S. and Hayward, G. (2001) Micromachined unimorphs and bimorphs. In: IEEE International Ultrasonic Symposium, 2001-10-07 - 2001-10-10.

A frequency doubled copper vapour laser (CVL) operating at an ultraviolet wavelength of 271nm has been used to cut miniature cantilevers in laminated composites incorporating at least one layer of the ferroelectric polymer polyvinylidene fluoride (PVDF). Devices have been fabricated from PVDF with thickness values in the range 9mum to 38mum. Laser vibrometer measurements show that the fundamental resonance frequencies of these devices correspond almost exactly with values obtained from mechanical beam theory. Ultrasonic transducers consisting of bimorph and unimorph arrays are currently being designed with the aid of a finite element model, which is not discussed.
