摘要： 介绍了体内微机电系统空心线圈电感的计算,主要对非同轴的线圈互感计算进行详细研究,分析了初次级线圈主要几何参数如轴向和径向距离、夹角、线圈半径等对互感的影响.计算结果表明：轴向距离和径向距离增大,互感均减小,但轴向距离对互感的影响要大得多；夹角越大,互感减小,夹角为90°时,互感几乎为0；当线圈半径变化时,互感有个最大值.同时给出一种三轴移动测试平台,可以快捷精确地调节线圈间的轴向径向距离和夹角,在此基础上建立了互感测试系统,测试结果与计算值是相符合的.

Abstract: The coreless coil inductance calculation of MEMS in human body was proposed, focusing on the mutual inductance of non-coaxial coils. The effects on the mutual inductance due to main geometric parameters, such as gap, obliquity and radius, were analyzed. The numerical results indicate that mutual inductance decreases with the increase of axial and radial gaps and the influence of axial gap on mutual inductance is much bigger than the radial one; with the increase of obliquity, mutual inductance decreases, and when obliquity angle is equal to 90°, it is nearly zero; when coil radius varies, mutual inductance has a maximum. Furthermore, a tri-axial moving platform is put forward in which gap and obliquity can be adjusted easily and accurately. On the basis of the above, a mutual inductance measuring system is established, and the testing results are consistent with the calculation.
