pH Sensing of Printed Flexible Sensors

This paper presents the fabrication and implementation of some of the printed flexible sensors develop with laser cutting technique. Different types of elastomeric and conductive materials were used to fabricate the electrodes and substrates of the sensor prototypes. The developed prototypes were then used as pH sensors to determine their behavior over a range of pH values at the acidic and basic spectrum. The behavior of these prototypes proved their potential to be used for electrochemical sensing in different health and environmental applications.
