A miniature mouthpiece rotational accelerometer has been developed to measure the angular acceleration of a head during vehicle crash or impact conditions. The device has been tested in the laboratory using a shake table and in the field using dummies and humans. The results of the testing show that while the accelerometer is sensitive to angular acceleration it is also sensitive to linear acceleration, and in practical applications a correction factor for linear accelerations must be applied to the rotational output.
