Purpose: This research explored the use of Wireless Micro Electro Mechanical Systems (MEMS) sensors to analysis the difference of badminton forehand cut vibration. Subjects: The elite athlete is ranked number 14 in the world and the sub-elite are ranked the third of group B in this Taiwan. Methods: Underneath the racket is placed a wireless MEMS sensors which includes a tri-axis accelerometer. The sample is taken on the frequency of 3333Hz. When athletes strike forehand cut racket, sensors capture measuring point of numerical data, and statistical analysis. Results: 1. Two of the contestants not worn and wore sensors in ball speed, paired t testing, no significant differences. 2. The number racket acceleration spectrum amplitude testing, the elite athlete had higher vibration frequency than sub-elite in X and Z asix. The sub-elite got 325Hz in Y asix; however, the elite athlete had no obviously performance. 3. From the test of racket vibration time, verification revealed that the elite athlete and the sub-elite had obviously difference. 4. The analysis of racket time zone, it indicated that athletes had obviously difference during the max and min average values on X and Z axis. The elite athlete stroke with the higher hitting and the ball felt in the front area than the sub-elite. Discussions: 1. Wearing sensors would not affect the athletes’ performance. 2. In the distribution rate of racket acceleration spectrum amplitude, the elite athlete had higher vibration in X and Z axis. 3. In the vibration time, it indicated that the elite athlete had shorter period than the sub-elite. The elite athlete was significantly better than sub-elite. 4. From the time zone of the racket, the max and min average in tri-axis got obviously difference paired F and t test. The elite athlete got less power in a flash hitting and got better control in striking.
