Abstract

A deformation collision sensor (10) comprises a deformable hollow space (12), with at least one acoustic sensor element (22) connected to the hollow space (12), with an evaluation unit (26) connected to the sensor element (22), and with a thermoacoustic actuator (24) connected to the hollow space (12) for coupling preferably standing sound waves (25) into the hollow space (12). The evaluation unit (26) is designed for evaluating signals (23) that are created in the sensor element (22) by the sound waves (25). The acoustic actuator (24) preferably emits sound waves (25) in the frequency range between 5 and 500 Hz.
