App note: Thermal mass flow sensors for gas and liquid applications

White paper from Integrated Device Technology on the emergence of MEMS thermal mass flow sensors. Link here (PDF) Flow meters represent the instrumentation of flow sensors and are used to measure the amount of flow that passes through them. There are in principal five different flow meter types: velocity flow, positive displacement flow, differential pressure […]

Teardown of a Piezoelectric vibrating gyroscope

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 MPU-6500 for example can be […]

App note: An Introduction to MEMS Microphone Specifications

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 create high performance microphones of […]
