Abstract

Smart components are increasingly of interest in
research and industry due to their wide range of applications. An
example of this is a current project of the Federal Excellence
Cluster MERGE, which is concerned with the development of a
center console that serves as a control element in an automobile
and is executing actions by touching it. In order to facilitate this
functionality, it is necessary to evaluate the electrical signals
generated by piezoceramic sensors regarding to the localization
of the impact. In this respect, various signal features are
investigated for their suitability using a support vector machine.
The results show that an impact localization can be realized by
the energetic consideration of the signals but has limitations in
the practical usability.
