The Memsic (analogue or digital) 1,2 & 3 axis, low power, low noise version contains a small heater in a silicon sealed cavity; thermocouples determines where the heated gas reaches within the cavity and the deflection off the centre is a measure of the acceleration applied to the sensor, thus the device is extremely useful in rugged, harsh environments where it is used to measure tilt, acceleration and rotation.

The InvenSense 3 axis, low power accelerometer (only available combined with the gyro) is sensitive to the direction in the plane of the die (by integrating two devices perpendicularly on a single die and adding another out-of-plane device three axes can be measured).
