| Sumario: | In this work the first attempt of developing a novel pressure sensor based on the use of ordered nanostructures embedded on a custom made PDMS optical fiber is shown. When building a nanostructure, the order highly affects its physical properties, including the optical ones. We intend to take advantage of this characteristic of these materials to build a pressure sensor based on the transmittance through a nanostructure and use for photonic touch sensing. To do this, a new device is developed, that consists of a waveguide built with PDMS, a flexible and transparent material in which we could build a nanostructure. On this work we have studied how to build these structures, building six of them with the cavity having a depth of near 250 µm and thickness of 200 µm or 500 µm. We have also seen how to build the nanostructure inside using the electrospray method, obtaining good results when mixing the colloidal nanoparticles with 2-propanol and also when applying heat to the waveguide during the process. |
