• Description:
  This paper introduces a robust electrochemical gas sensor featuring room temperature ionic liquid (RTIL) as electrolyte and porous polytetrafluoroethylene as a flexible substrate. Using a planar-electrodes-on-permeable-membrane structure, a flexible RTIL sensor with 9.6 mm2 sensing area is microfabricated. The sensor's response to oxygen is measured, achieving sensitivity of 0.48 uA/% O2, a linearity of 0.997 R2 in range of 0%-21% O2, and limit of detection of 0.08% O2. The reported sensor structure and fabrication process enable realization of sensor arrays for multi-gas monitoring in a low power, miniaturized, and wearable system platform.
