采用静电激励和静电检测，通过罗伦兹力的反馈将磁场的大小转变为频率输出。

Transforming the output of frequency to the magnetic field through the feedback of Lorentz force, this device was capacitively excited and the signal was capacitively detected.

因此，为获得优化的设计，计算洛伦兹力和磁致伸缩力以及选择合适的工作方式变得尤为重要。

It is important to determine both the Lorentz and magnetostriction forces and select the appropriate working manner for achieving an optimized design.
