Professor Andrew Flewitt
Professor Andrew Flewitt is pleased to consider applications from prospective PhD students.
I work in large area electronics and MEMS devices, with a particular focus on acoustic wave devices using thin film piezoelectrics. There are two applications of these. Surface acoustic wave (SAW) devices can be used to make microfluidic pumps without any moving parts, where a force acting on a fluid is provided by an acoustic wave. Film bulk acoustic resonator (FBAR) devices are small-scale gravimetric sensors which are capable of edecting mass changes on their surface down to 1 fg in mass. With selective functionalisation of the surface (typically 100×100 µm in area) it is possible to detect specific biological molecules.
