我们提出了一个完全实用的TunaDrive压电电机。它由一个中心压电叠层夹在两个臂压电叠层和两个腿压电叠层，分别，然后夹在一对平行的抛光蓝宝石棒和弹簧夹紧。它的工作原理是交替快速扩展和收缩臂/腿堆栈，同时缓慢扩展/收缩中央堆栈。其关键在于，足够快的膨胀和收缩能使翼叠的两个滑动摩擦力很好地抵消，从而使总滑动摩擦力为
We present a completely practical TunaDrive piezo motor. It consists of a central piezo stack sandwiched by two arm piezo stacks and two leg piezo stacks, respectively, which is then sandwiched and spring-clamped by a pair of parallel polished sapphire rods. It works by alternatively fast expanding and contracting the arm/leg stacks while slowly expanding/contracting the central stack simultaneously. The key point is that sufficiently fast expanding and contracting a limb stack can make its two sliding friction forces well cancel, resulting in the total sliding friction force is
