在此之前，表面声波直线电机已被证明和其确切的预加载条件的调查。在此基础上，设计了多点接触滑块，并进行了试验研究。成功地获得了0.45 N的最大输出力，是初步实验中获得的450倍。简单的模拟结果预测，更大的推力将可通过增加实际接触点面积，而不改变滑块和定子的尺寸。计算的输出力为10 N，大约是实验观察到的20倍。为了实现接触表面的所需定子纹理，硅微加工技术或其它常规方法将是适用的。
Previously, the surface acoustic wave linear motor has been demonstrated and its exact pre-load conditions investigated. Based on this previous research, multi-contact-point sliders were designed and tested. A maximum output force of 0.45 N, 450 times that obtained in preliminary experiments, was successfully obtained. Simple simulation results predicted that much larger thrust would be available by increasing the actual contact point area without changing the slider and the stator dimensions. The calculated output force was 10 N, roughly twenty times that observed experimentally. To realize the required stator texture of the contact surface, a silicon micro-machining technique or other conventional methods would be applicable.
