The Kionix Advantage
Kionix technology provides for X, Y, and Z-axis sensing on a single, silicon chip. One accelerometer can
be used to enable a variety of simultaneous features including, but not limited to:
Hard Disk Drive protection
Vibration analysis
Tilt screen navigation
Sports modeling
Theft, man-down, accident alarm
Image stability, screen orientation & scrolling
Computer pointer
Navigation, mapping
Game playing
Automatic sleep mode
Step counting (pedometer)

Theory of Operation
Kionix MEMS linear tri-axis accelerometers function on the principle of differential capacitance.
Acceleration causes displacement of a silicon structure resulting in a change in capacitance. A signal-
conditioning CMOS technology ASIC detects and transforms changes in capacitance into an analog
output voltage, which is proportional to acceleration. These outputs can then be sent to a micro-controller
for integration into various applications.
