This paper is a research plan of a PhD candidature in the area of measurement optimisation for complex microsystems in sport applications. The research will be conducted at Swinburne University, in collaboration with The Australian Institute of Sport, Griffith University and CRC for Microtechnology. The project was commenced on the 27th of May 2002 and the expected completion date is on the 27th of May 2005. The purpose of the research is to investigate and resolve some of the issues with measurement systems in sport applications. The expected outcome of this research is to make improvements in current measurement system design and implementation. The proposed benefit to The Australian Institute of Sport is that better measurement systems with more accurate and useful data will be available to coaches at the highest level of competition to distinguish and enhance an athlete`s performance.
