This paper shows a proposal of servo type jerk sensor and its application to air type anti-vibration apparatus as feedback (FB) sensor. Servo type sensor of displacement, velocity, and acceleration can be realized by changing FB according to a law of differential and integral calculus. Thus, servo type jerk sensor is incarnated by using integral FB. Applying the three types of FB in addition to integral FB makes jerk sensor stability behavior. In order to confirm that prototype sensor can use not only observation sensor but also FB sensor, this sensor applies to air type anti-vibration apparatus. Time and frequency responses show that machine impedance operation for the air type anti-vibration apparatus (AVA) using jerk FB varies the natural frequency. However, in the result, it also confirmed that phase characteristic of the jerk sensor is not sufficient. Due to this, plate spring of the pendulum in the sensor is stiffened. In the result, phase and sensitivity characteristics of jerk sensor are improved. Then, the sensor applies to the air type AVA again. Machine impedance operation for the AVA is confirmed sufficiently. From these results, it confirms that jerk sensor is realized and employs not only observation but also feedback sensors.
