Fibre devices enabled by hollow core fibre technology by Zang, Jichao

“…Up to now, there have been intensive studies focused on the guiding mechanism and background loss reduction in single hollow-core anti-resonant fibres (HAFs), and the HAFs have been explored in a wide range of applications including high power pulse delivery, nonlinear gas-light interactions, interferometric sensing, telecommunications networks, and optical fibre gyroscopes. The technological progress in the past has shown the readiness and ambitions of the technology for progression to device development. …”

Wearable wireless ultrasonic sensors for human gait analysis by Ashhar, Karalikkadan

“…Recent advancements in the field of micro-electromechanical systems led to the use of inertial measurement units like accelerometers and gyroscopes for human motion tracking. However, the unavoidable integration drift in the calculated position values made the independent use of these systems unfit for human motion capture. …”

Multi-sensors for realization of home tele-rehabilitation by Seanglidet, Yean

“…It is the result of accumulated errors over the integration of the gyroscope signal to calculate the angular displacement, in other words, the orientation of the limb, in the motion tracking application. …”
