Measurement of the foot and shoe interface pressure underpins a number of important applications. Abnormal pressure may indicate instability in gait, risks of diabetic ulceration and many other biomedical and sports applications. As the current foot pressure sensors in the market exhibit many limitations, a new sensor design based on the more promising MEMS technology was therefore explored. As such, this paper reports the analysis and optimization of a MEMS pressure sensor for foot pressure measurement. The pressure sensor had a high linearity output with pressure span of more than 2-MPa. This characteristic indicates excellent potential for a wide spectrum of biomechanical activities.
