Researchers from Spanish National Research Council (CSIC), Catalan Institute of Nanoscience and Nanotechnology (ICN2-BIST), Biomedical Research Centre Network (CIBER) and Catalan Institution for Research and Advanced Studies have recently developed the first stretchable plasmonic enhanced wrinkled Fabry-Perot cavities showing extremely high sensitivity to mechanical deformations. This novel technology enables developing new stretchable opto-mechanical devices with higher mechanical sensitivity, tunability and versatility.
Manufacturers in the field of sensors for detection of mechanical deformations, pressure or forces are being sought to collaborate and/or exploit the existing know-how through a patent license agreement.
The invention describes a novel opto-mechanical device with ultrahigh sensitivity to strain deformations showing 16-fold lower detection limit than state of the art optical strain sensors.
The device is based on a novel stretchable plasmonic enhanced wrinkled Fabry-Perot cavity, in which mechanical deformations simultaneously generate large spectral shifts in the cavity resonances and variations their quality factor. This combination enables the new sensing parameter “spectral area” boosting the sensitivity to detect the mechanical deformations.
These devices are fabricated via an innovative self-assembled and self-embedded process to integrate the arrays of plasmonic nanostructures at controlled depths in the elastomer film and to generate the cavity wrinkles by exploiting the catalytic properties of the nanostructures. This novel technology opens the path to develop new stretchable opto-mechanical devices with higher mechanical sensitivity, tunability, and versatility for new strain, force and pressure sensors in wearable and/or industrial applications, mechanically tunable optical filters and modulators, and mechanically controlled translucent elastic films.

The Spanish National Research Council (CSIC) is the largest public institution dedicated to research in Spain and the third largest in Europe. Belonging to the Spanish Ministry of Economy and Competitiveness through the Secretary of State for Research, Development and Innovation, its main objective is to develop and promote research that will help bring about scientific and technological progress, and it is prepared to collaborate with Spanish and foreign entities in order to achieve this aim. According to its Statute (article 4), its mission is to foster, coordinate, develop and promote scientific and technological research, of a multidisciplinary nature, in order to contribute to advancing knowledge and economic, social and cultural development, as well as to train staff and advise public and private entities on this matter.
