This work aims to humidity and VOCs measurement using TEOS films or TEOS/HFE composites. Films, exposed or not to ultraviolet, were tested on cycles of relative humidity ranging from 25% to 85% and VOCs interference were also evaluated. TEOS films showed good reproducibility up to 85% relative humidity but quick reaction on 90%. The best detection limit was(More)
TEOS and/or TEOS/HFE plasma polymerized thin films, exposed or non-exposed to ultraviolet (UVC) radiation, were obtained on gold electrodes and tested for electrochemical measurements. All films presented good performance on electrochemical measurements. The electronic signal does not change significantly after 24h on physiologic serum but thin TEOS films(More)
