Quantifying human movement during sporting activities is of great interest since it allows trainers to assess the athlete's performance, their rehabilitation and injury recovery. Due to the environment limitations of laboratory testing, research has been focused on the development of Micro electromechanical (MEMS) based inertial sensors with the objective of reducing the sensors in size and power requirements, and making the technology widely available at low cost. The aim of this paper is to present an analysis about the growth of wearable technology, notably, inertial sensors, and the use of a common base platform for different sports application fields including research, education, commercial and servicing.
