title: Screen-printed dissolved oxygen sensor based on cerium oxide-supported silver catalyst and polydimethylsiloxane film.
abstract: A screen-printed dissolved oxygen sensor was fabricated using cerium oxide-supported silver catalyst and polydimethylsiloxane (PDMS) film.  A PDMS film of 3 µm thickness showed good permeability for oxygen and impermeability for hydrogen peroxide.  The calibration curve has shown a linear relationship with a correlation coefficient of 0.996 for the dissolved oxygen concentration.  The sensitivity and detection limit of the present sensor were calculated at -158 µA mM(-1) and 8.4 µM, respectively.
