- *Abstract
-
Using micromachined gyroscopes to measure angular velocity is becoming increasingly common in applications ranging from ballistics and crash-testing to mobile micro-robotics. Although a variety of MEMS gyroscopes are commercially available, their dynamic range, power requirements and package size are sometimes not well-suited to the applications.
To address these problems, researchers at the University of California at Berkeley have developed a radically new type of angular rate sensor. Based on the biological mechanism of flying insects, this Berkeley biomimetic gyroscope uses piezoelectric actuators to measure angular velocity.
There are several advantages to using this biomimetic approach over MEMS-based designs. First, the biomimetic gyroscope has a much greater dynamic range. It can detect angular velocities from as low as tens of degrees per second to as high as hundreds of thousands of degrees per second -- three orders of magnitude higher than most MEMS gyroscopes. Second, in applications involving rapidly moving objects, this Berkeley gyroscope requires much less power than the MEMS alternatives.
