Abstract: A torque sensor includes an input rotation component, which rotates with a steering column input shaft and is provided with a first conducting part, an output rotation component which rotates with a steering column output shaft and is provided with a second conducting part, and an electromagnetic carrier positioned in a positionally fixed manner and provided with a magnetic field generating component and a magnetic field detection component. The magnetic field generating component generates a magnetic field penetrating the first conducting part and the second conducting part, the magnetic field detection component detects a change in the magnetic field caused by a change in the positions of the first and second conducting parts in the magnetic field when the steering column is under torsional stress, and the steering torque is determined on the basis of the detected change in the magnetic field.

Abstract: The invention discloses a metal nanoparticles/nanocellulose composites-based non-enzymatic electrochemical glucose sensor, comprising a three-electrode system composed of a working electrode, a counter electrode, and a reference electrode. The surface of the working electrode is coated with a metal nanoparticles/nanocellulose composites. The surface of the nanocellulose is modified with a strong cationic conducting polymer. The invention promotes the sensitivity and selectivity of glucose sensing with the linear range of 4 ?M-15 mM and the detection limit of 1.4 ?M. Therefore, the sensor possesses high sensitivity, high response speed, stable performance and high anti-interference ability. The preparation method of the metal nanoparticles/nanocellulose composites-based non-enzymatic electrochemical glucose sensor is simple and the cost is low. And enzyme is introduced into the preparation process.
