An automated method and system of determining movement and/or deformation of an anthropomorphic test device (ATD). The method and system includes an acoustic transmitter device located on a first region of the ATD and an acoustic receiver device located on a second region of the ATD. An electric field is provided in communication with the acoustic transmitter to activate the acoustic transmitter for generating mechanical waves to be received by the acoustic receiver. Relative locations of the acoustic transmitter device and the acoustic receiver device are determined by the time of flight of the generated mechanical wave traveling from the acoustic transmitter device to the acoustic receiver device while the first region of the ATD and/or the second region of the ATD are subjected to movement and/or deformation; and determining movement and/or deformation data of the second region of the ATD. Information may be transmitted that represents the movement and/or deformation data of the second region, or information may be presented that represent the movement and/or deformation data of the second region on a display.
