Three‐Dimensional Anomalous Hall Sensing Enabled By Spin–Orbit Torque Driven Domain Reconfiguration In Chiral Multilayers

Advanced Functional Materials, EarlyView.
A three‐dimensional magnetic field sensor is realized in chiral W/CoFeB/MgO multilayers, where spin–orbit torques reversibly reconfigure homochiral stripe domains. The symmetry of the torque enables offset‐free in‐plane sensing, while the reproducible domain reconfiguration extends the linear out‐of‐plane range. An anomalous Hall readout delivers large‐

A wheelchair ergometer with a device for isokinetic torque measurement

Journal of Rehabilitation Medicine, 1989
A wheelchair ergometer has been developed for the study of wheelchair work. At each propulsion the peak torque can be examined, and there is an opportunity to directly study angular amplitude, power output, work etc. The physical capacity of the subject as well as the importance of chair adjustments upon performance can be evaluated.
