The forth research area deals with the study of combined properties of nanostructured networks leading to multifunctional applications. The group is particularly interested in the overlap between mechanical properties and energy storage. In the past, it has developed methods to produce a range of flexible, tough electrodes by eliminating metallic current collectors. It has also produced structural power composites, i.e., combining load-bearing properties with energy storage functions (Figure 4). At the materials level, the aim is to better understand the role of damage tolerance in electrochemical cyclability. Additional areas of interest are the use of pierzoresistive nanostructured networks for chemical and strain sensing in structural composites.
