  1. 1. Micromachined Three-Axis Accelerometers and Sensor Readout Electronics

    Författare :Henrik Rödjegård; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three axis accelerometer; sensor readout; inertial sensors; gyroscope; MEMS; digital feedback; capacitive readout;

    Sammanfattning : Miniaturized, MEMS-based, inertial navigation systems are used to track the position of moving objects without an external reference system. Several existing and future applications such as indoor navigation, stability control of vehicles, active prostheses or training aids for sportsmen would benefit from the small size and the low cost of micromachined inertial sensors.
