PROJECT


Summary

Elastomers, in everyday language rubber, show significant potential in high technology applications. Elastomers may be used in future for the conversion of the mechanical energy of water waves into electrical energy. Elastomers are used as mechanically deformable capacitors, able to convert mechanical into electrical energy in a cycle, similar to the Carnot cycle in thermodynamics. The potential of the proposed technology is huge, the worldwide electricity generation may be met by converting the mechanical energy of water waves into electrical energy.

Scientific

The work in the project helped breaking new scientific ground in the dielectri elastomer field and in stretchable electronics. Noteworthy is a review for the 25 anniversary of Advanced Materials, where results obtained in this FWF project has been highlighted by our team. The paper is also listed as highly cited in ISI Web o Knowledge.

NEW METHODS

Our research is multidisciplinary, combining mechanical and electrical engineetring with applied physics. Our research work contributes to the development of these three distinct research areas. We follow a philosophy of publishing which may best be described by “less is more”, and we believe that this approach has been successful in the project with a total number of 13 papers having received more than 600 citations in Google Scholar..

PERSONNEL

During the course of the project several master, PhD students and postdocs worked on specific aspects of the project. The students started working in the project as master students, and continued to work as a PhD student or as a postdoc.

Publications


Within this project, 13 publications appeared in peer-reviewed journals. The total number of citations for these papers is 629 on Google Scholar (checked on April 25, 2016), resulting in an average number of 48 citations per paper. On ISI Web of Knowledge, 4 of the published papers are listed as highly cited [1,6,9,10].
