This research explored the use of Wireless MEMS Sensors System to analysis of badminton forehand striking clear racket vibration. Purpose: analysis of the domestic player “national group A” and the second best player “group B” striking forehand clear racket of the divergence and the stability. Objects: the player from currently under test world rank 14 – participation in 2012 the 30th London Olympic Games - and the second best player currently rant match in group B third place. Method: to place sensor wireless MEMS sensors in the racket points; each measurement point contains three-axis acceleration sensor chip. When players strike forehand clear racket, each chip captures sensor measuring point of numerical data, and statistical analysis. Result: 1. two of the contestants not worn and wear sensors in ball speed, paired t- testing, no significant differences. 2. The number racket acceleration spectrum amplitude, x axis is inaccuracy with y axis. 3. in 15 times racket acceleration spectrum amplitude, the national group A player has more vibration between 443 to 482 Hz and group B player gets vibration between 299 to 417 Hz. 4. the max compare of three-axis area, the group A player and the group B player have obviously difference. 5. The racket vibrating time of F and T testing, group A player’s vibrating time is shorter than group B’s. Conclusions: 1. the racket acceleration spectrum amplitude and the racket vibration have their diverseness. 2. Group A player and group B player have different characteristics of vibration.3. Group A player has powerful force than group B player. 4. From the vibration of the racket, it showed that group A player forces the power shorter than group B player, which means group A player release power after she hit but didn’t group B player.
