Excerpt

This work proposes a highly novel centrifugally spun lanthanide doped nonwoven fibrous mat as a non-contact optical pressure sensor with a wide linear dynamic range and good pressure sensitivity. The sensor properties are based on the spectral shift, broadening and intensity enhancement of Ce 3+ ion in Ce doped PVDF fiber upto significantly high pressure. Two different systems: Ce (NO 3) 3· 6H 2 O and (NH 4) 4 Ce (SO 4) 4· 2H 2 O doped PVDF flexible fibers (CeN-PF and CeS-PF) were produced using the Forcespinning® technique …
