Teardown of a Piezoelectric vibrating gyroscope

Wednesday, February 6th, 2019

Kerry Wong did a teardown of an old analog piezoelectric vibrating gyroscope: Gyroscopes nowadays are based on micro-electro-mechanical systems (MEMS) technology. They are low cost and extremely miniaturized. A device combing both a three-axis gyroscope and a three-axis accelerometers (sometimes these devices are referred to as 6DOF devices) such as the...

App note: An Introduction to MEMS Microphone Specifications

Sunday, March 27th, 2016

An application note from Cirrus Logic on their MEMS microphones, which are small and perfect for wearables devices. Link here (PDF) MEMS microphones are small form factor microphones, which translate acoustic sound pressure input into an electrical output response. They utilise the silicon wafer processes from the microelectronic industry to...
