The best paper/presentation award was granted to Johan Toftekær for the development and experimental verification of a new tuning method for resonant piezoelectric absorbers. The method is based on simple measurements of the absorber’s electric current and voltage response. It specifically accounts for the influence from non-resonant vibration modes, whereby the tuning of the piezoelectric shunt (electric circuit) becomes sufficiently precise for it to be realized by passive electronic components. Single- and multi-mode vibration suppression of a plate was finally demonstrated.

The ICAST conference serves as an international forum for promoting exchange and discussions on recent advances in the multidisciplinary field of smart materials and structures. The conference particularly emphasizes transformations of innovative scientific realizations in smart materials and structures to engineering applications.
