Technology Description

The present invention discloses a novel soft stretchable enhanced Fabry-Perot (FP) cavity. The FP cavity is composed of arrays of nanostructures, showing plasmonic and/or dielectric resonances, which are self-integrated into elastomeric films by a highly innovative self-swallowing process. The process that the inventors disclosed shows the spontaneous swallowing of a plurality of metallic, dielectric or dielectricmetal coated nanostructures into the elastomer matrix and the wrinkle formation.
The opto-mechanical response, of the self-embedded arrays of nanostructures, provides theoretical and experimental demonstrations of the plasmonic enhanced and Fabry-Perot optical modes, together with the influence of the wrinkled elastomeric films surface, as polydimethylsiloxane (PDMS) surface.
The invention describes a process to obtain the material, a sensor comprising an active layer of the material, and their use as part of a device to change light transmittance.

Potential Benefits

The present invention describes a new material with opto-mechanical behavior that solves the problems of the devices and methods of the state of the art.
This innovative technology allows the development of new stretchable optical devices with larger mechanical tunability, versatility and sensitivity, as well as to simplify their fabrication and improve the robust integration.


To be determined during further development.
