I’ve always been fascinated by electronic sensors. The idea of being able to measure and interact with the physical world appeals to the ten-year-old inside me. Not so long ago, if you needed to measure some physical quantity as an input to your system, you bought an analog sensor, hooked up your own signal conditioning circuitry, and fed the result into a dedicated analog-to-digital converter. Over time, engineers demanded, and got, self-contained products which handled those signal conditioning and conversion tasks for them. Continue reading

Top 30 MEMS ranking: Total revenues slip 5%, but innovation still spurs growth for many

Contributed by Jérôme Mouly, MEMS Technology and Market Analyst,Yole Développement

Total MEMS revenues from the Top 30 MEMS suppliers tracked by Yole Développement slipped 5% in 2009, as the worldwide downturn hit consumer and automotive sales. But innovation still continued to sell. Companies with new, high-end products managed healthy growth, led by an eye-popping 500% increase at InvenSense, Inc., rapidly building up a $95M business in gyroscopes for consumer electronics.

Sensors, sensors everywhere: MEMS and the “Internet of Things”

Robert MacManus posted an interesting piece on ReadWriteWeb recently (see 2010 Trend: Sensors & Mobile Phones) in their series on the “Internet of Things”–where devices are connected to the Internet to provide us with more data and functionality. Although he doesn’t call it MEMS by name, he makes the point that cell phones are becoming much more than communications devices; cell phones and mobile devices are essentially pocket-sized platforms for sensors. And, yes, many of these sensors are MEMS devices! Continue reading
