Microfluidic devices (MFDs) are microchips for handling liquids in channels smaller than the width of a human hair allowing reduced consumption of reagents and integration with biosensors. The microfluidics market for biodiagnostics and pharmaceuticals was valued at $1.59 billion igrowing (Markets and Markets, 2013) . Traditional methods of manufacturing MFDs are too slow and costly to meet the demands of a growing market. A need for rapid prototyping and scalable production is indicated.
We propose the construction of novel ultrasound transducer structures based on existing MEMS technology that has been in development through collaboration between Micralyne and Prof. Roger Zemp. We will be exploring linear array transducers intended for medical imaging, and individual transducers for automotive use for ultrasound range finding. We will undertake the design, modelling, fabrication, packaging, and testing of the devices. The end goal is to produce commercially-viable transducers that may be used as replacements for the current generation of piezoelectric-based transducers.
he ultimate objective of this project is to design and develop a signal/noise analyzer to improve the reliability and efficiency of EM-based measurement-while-drilling (MWD) tool within various strata formation under high temperature, deep drilling environment. In order to analyze the received signal contaminated by surface and underground noise, it is essential to understand the electrical and magnetic field behavior with respect to rock formation and the transmitted signal properties including frequency, amplitude, and phase.
The project concentrates on MEMS (Micro-Electro-Mechanical Systems) fabrication process optimization. MEMS devices comprise suspended structures, such as cantilevers, gyros, membranes, etc., which are created by removing sacrificial material around them in order to have these structures released to perform their designated function. Currently, these structures are being released with the use of either dry etch or chemical vapor techniques. Wet chemistry release of suspended structures is favorable: minimized costs, parallel process and most importantly reduced impact on the environment.
Le succès commercial et la pérennité sociale d’une PME – bref, son âme – résident dans ses personnes et leurs compétences. Une gestion stratégique efficace des compétences d’une PME passe donc nécessairement par la bonne gestion stratégique de ses personnes ou, plus concrètement, des façons dont ces derniers décident librement et en toute conscience de mettre à contribution leurs compétences au bénéfice de l’entreprise (c.-à-d. expertise, conscience professionnelle, mécanismes personnels de création de sens).
In this collaborative project with Comtek Advanced Structures, the PhD Intern will develop methodologies to model and predict the propagation of acousto-ultrasonic and ultrasonic sound waves in advanced composite materials for aerospace applications. These sound waves can be used to detect damage and degradation in aircraft structures.
