Bodysuit may help researchers to improve sporting activities

The £50,000 suit, which has previously been used as a tool by film makers and the military, is a 3D human kinematic camera-less measurement system that can communicate wirelessly with a computer.

The suit is being used at Sunderland for a range of research projects by both lecturers and students in areas such as biomechanics, sports science and rehabilitation.

In the field of biomechanics, the system could enable the detailed analysis of a person’s moving body parts in order to identify ways of improving overall physical performance.

The system generates an on-screen avatar, which represents the person wearing the Xsens MNV Biomech suit.

Dr Robert Hogg, a biomechanics expert from Sunderland University, told The Engineer: ‘3D motion-capture has historically been done with video systems. This technology is different because it uses… MEMS [microelectromechanical systems] sensors.’

Each of the 17 sensors on the suit consists of an accelerometer, a magnetometer and a gyroscope. Together they measure acceleration, postural position relative to the magnetic field of the Earth and orientation.
