Evaluation of Signal Features used for Impact Localization on a Center Console with Piezoceramic Sensors
Smart components are increasingly of interest inresearch and industry due to their wide range of applications. Anexample of this is a current project of the Federal ExcellenceCluster MERGE, which is concerned with the development of acenter console that serves as a control element in an automobileand is executing actions by touching it. In order to facilitate thisfunctionality, it is necessary to evaluate the electrical signalsgenerated by piezoceramic sensors regarding to the localizationof the impact. In this respect, various signal features areinvestigated for their suitability using a support vector machine.The results show that an impact localization can be realized bythe energetic consideration of the signals but has limitations inthe practical usability.
