In the paper, we first describe the fabrication process of the proposed sensing device and then we analyze its performance in terms of thermal sensitivity and deformation detection capability. In particular, FBGs were embedded in polylactic acid (PLA) rectangular patches that confer greater strength to the bare FBG and enhance their sensing capabilities. We show that the patch thickness, by increasing the distance between the optical sensor and the neutral axis of the structure where it is fixed, provides a gain factor in the device sensitivity to deformation. These results encourage the application of FBGs embedded in 3D-printed patches in the field of the structural monitoring where, by efficiently selecting patch dimensions, in particular the thickness, it is possible to improve the sensor robustness and, contemporary, the deformation sensitivity with respect to bare FBGs.","PeriodicalId":131383,"journal":{"name":"2020 Italian Conference on Optics and Photonics (ICOP)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131742047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process exploits femtosecond laser pulses and a photo resist that is transparent at the laser wavelength (515 nm) but absorbs two photons at high intensity to polymerize, resulting in the possibility of fabricating devices for advanced photonics and biomedical applications. In this paper, the manufacturing of 3D microstructures through two-photon polymerization is discussed.","PeriodicalId":131383,"journal":{"name":"2020 Italian Conference on Optics and Photonics (ICOP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127165698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
