摘要：

The sensitivity of a commercial torque transducer under oscillatory shear conditions is extended by about a factor 3-5 into the small torque region. This increased sensitivity is a result of a straightforward data treatment in the time domain termed "on the fly oversampling". This method is enabled by the emergence of modern ADC-cards. The underlying ideas of oversampling together with a first experimental verification of this method are described in detail.
