Device drivers major hurdle to growth of MEMS sensors
Cell phones have long been targeted as a major end-use application for MEMS (MicroElectroMechanical Systems) sensors, and accelerometers in particular, but widespread integration hinges on the development of device drivers, not the sensors themselves, according to Bourne Research. The market research firm reports that MEMS suppliers have had it relatively easy selling sensors into markets such as automotive (the mainstay of the industry to date), since those customers typically write their own code for device drivers. However, consumer electronics is turning out to be an entirely different ballgame.
"At this point, it appears that handset manufacturers are still not convinced that MEMS sensors are worth spending the money necessary to create the device drivers needed, mostly because there's uncertainty about whether consumers will like MEMS-enabled features enough to pay more for them," says Marlene Bourne, Principal Analyst with Bourne Research. "As a result, these manufactures currently expect a total solution, one which MEMS sensor suppliers are unable to provide, nor can they do so on their own. Partnerships will be required, but those have their own issues."
Bourne Research reports that the need for device drivers provides an opportunity for those who specialise in embedded software development; however, partnerships with MEMS suppliers may be difficult to put into place for both start-ups and large semiconductor players alike. Given the potential system-wide impact of MEMS sensors, and the number of device drivers required to accommodate all of the possible functions, it's a tough challenge; and there's a lot at stake for MEMS suppliers -- integrating sensors into just ten percent of all mobile phones shipped annually would be a major coup for the industry. Bourne Research has identified two approaches that may very well be the best solution for all parties involved.
