You have a few choices (in the broad sense):

3-Axis Accelerometer:

3-Axis Gyroscope:

3-Axis Magnetometer:

Note that I just picked SparkFun to give you an idea of what you are looking for, and the wikipedia links so you know what each is for (and how they differ in operation). Note that depending on what you are looking for, level of accuracy, etc - you may need to use more than one of the above sensors, and integrate the results.
