We designed a flexible pickup coil for torque sensors in which the offset is reduced as a result of the asymmetric structure, which was created in order to obtain an easy connection. The mutual inductance was calculated for all the possible coil patterns of an asymmetric configuration, and the coil pattern that exhibited the lowest mutual inductance was selected the best design for the pickup coil. In addition, the performance of a flexible pickup coil incorporating this design was evaluated by observing its offset voltage, response to the uniaxial magnetic anisotropy, and input-output characteristic. The results showed that the offset voltage was lowest in an asymmetric coil pair. The response to the uniaxial magnetic anisotropy showed an output pattern as the axis torque sensor. The input and output characteristics almost accorded with those of a conventional symmetric model coil pair.
