MEMS (micro-electrical-mechanical systems) are rapidly becoming hot items in the electronics market. Consider the rather amazing controllers for WII games. These provide a degree of haptic feedback, partly based on the MEMS inside. Your iPhone or GameBoy have MEMS devices that allow realistic banking and turning on screen – again based on gyro feedback from MEMS devices.
Consider putting this micro-gyro capability into a heading hold and wing leveler device in an electronic certified flight instructor envisioned by the CAFE Foundation, and you can see why this technology holds promise for safer flight and expanded light aircraft capabilities.
Eagletree has a range of telemetry and monitoring products for model aircraft that combine this technology with sophisticated radio gear, including video capabilities, and you have a powerful tool for development.
