Arregui %J Sensors %D 2006 %I MDPI AG %R 10.3390/s6060578 %X A fiber optic sensor for Volatile Organic Compounds (VOCs) detection has beendeveloped and characterized for some organic gasses. The sensor is based on a novelvapochromic material, which is able to change its optical properties in presence of organicvapors in a reversely way. A nano Fabry Perot is constructed onto a cleaved ended opticalfiber pigtail by Electrostatic Self Assembly method (ESA), doping this structure with thevapochromic material. Employing a reflection scheme, a change in the intensity modulatedreflected signal at 850 nm have been registered. The response of the sensor has beenevaluated for five different VOCs, and a deeper study has been made for vapors of threedifferent alcohols. %K Fiber optic sensor %K Volatile Organic Compound %K Vapochromic complex %K Electrostatic Self Assembly method %K nanocavity %U http://www.mdpi.com/1424-8220/6/6/578
