摘要：

A simple torquemeter has been developed with a sensitivity exceeding 10(-13) Nm when using a 13-mu m-diam glass fiber and a low-mass suspension. The maximum twist angle of the fiber is constrained by the choice of its diameter to similar to 1 degrees. This angle is measured using a light, mirror, and split silicon photodetector, and is proportional to the torque on a sample in a rotating dc magnetic field. (C) 1999 American Institute of Physics.
