Sadly, MEMS made this kind of sensor obsolete, but we appreciate the look under the hood. Indeed, hooked the output of the sensor to a wonderfully old-school VOM whose needle wiggled with the slightest movement of the sensor. probed the innards of the sensor while powered up and discovered a 22 kHz signal on the piezo element this vibrates the bar in one plane so that when it rotates, it exerts a force on the support arms that can be detected. In this device, found that a long, narrow piezoelectric element spans the long axis of the sensor, suspended from what appears to be four flexible arms. The device is classified as a Coriolis vibratory gyroscope (CVG) which, as the name implies, uses the Coriolis effect to sense rotation. The video below shows a teardown of the sensor, huge by MEMS standards but still a marvel of micro-engineering. Actually, it’s kind of creepy when you think about it.īut before nano-scale MEMS inertial sensing came along, lots of products needed to know their ups from their downs, and many turned to products such as this vibrating piezoelectric gyroscope that found in an old camcorder. With MEMS chips, your phone can detect the slightest movement, turning it into a sensitive sensor platform that can almost anticipate what you’re going to do next. There’s no doubting the wonders that micro-electromechanical systems (MEMS) technology have brought to the world. ![]()
