Speech Tile: Flexible hydrogen sensor based on Pd/TiO₂ nanofilm with fast response

Abstract: Flexible hydrogen sensors based on palladium (Pd) and titanium dioxide (TiO₂) nanofilm on poly(dimethylsiloxane) (PDMS) substrate have been demonstrated. We have prepared PDMS using anodic aluminum oxide template and researched the performance of Pd/TiO₂ nanofilm based hydrogen sensors with different thickness of TiO₂. The sensor with 6nm thickness of TiO₂ has demonstrated the best performance with a response/recovery time of 1.6 s/6 s at 0.2% hydrogen concentration, respectively.
