Multi-stimuli responsive silicone composites for switchable dual-function transducers
Project status: Ended
About Objectives Results Dissemination Team Contact

Establishing and optimizing the appropriate silicone formulation and optimizing the procedure for embedding the  metal complex in the silicone matrix led to multiple stimuli-responsive elastomeric composites reported for the first time in the literature. It has been shown that these materials can have a dual role in actuation systems, both generating the electromechanical response and sensing the breakdown voltage. Also, the composites were successfully tested as flexible thermochromic display. The developed technology is new, original, and has been the subject of a patent application. The fundamental results were presented at four international conferences and were the subject of two scientific articles, one submitted for publication and one in progress.
