  • Patent number: 7992438
    Abstract: The present invention relates to a multiaxial gyroscope, which comprises a vibration-sensing device, a plurality of elastic connecting parts, a first substrate, and a plurality of electrodes. The first ends of the elastic connecting parts are adapted on the periphery of the vibration-sensing device. The sidewall of the first substrate connects with the second ends of the elastic connecting parts. The plurality of electrodes is located on the periphery of the vibration-sensing device and is opposite to the plurality of elastic connecting parts. The vibration-sensing device comprises a ring and a plurality of vibration blocks. By means of the vibration blocks, the sensing area as well as the driving amplitude of the gyroscope can be increased effectively. Thereby, the intensity of the sensed signals of the gyroscope can be enhanced.

  • Patent number: 7210351
    Abstract: A micro accelerometer including a plurality of proof masses is provided to detect the acceleration of the first axis, the second axis and the third axis. The disclosed micro accelerometer has the advantages of close loop control, mechanical decoupling, and not relying on high aspect ratio manufacturing technology.

  • Patent number: 7155978
    Abstract: A micro angular rate-sensing device is provided. A vibrator, having a plurality of proof masses connected to a ring, is arranged in a first base. Flexible supporting members connect to the vibrator to suspend the vibrator in the first base. Electrodes drive the vibrator to oscillate and control the oscillation mode of the vibrator in driving mode. Planar electrodes are arranged relative to the proof masses on a second base. The motion of the proof masses relative to the planar electrodes is sensed through the capacitance between the proof masses and the planar electrodes. The resonant structure with greater mass of the device generates greater Coriolis force and increases the sensing area. Thus, the intensity of sensed signals and noise-signal ratio are greatly increased. Furthermore, the device does not rely much on high aspect ratio manufacturing technology. Thus the manufacturing cost is reduced and the yield rate is increased.
