Abstract: This invention provides an extended gate ion-sensitive field effect transistor as a pH sensor for measuring the pH value of a solution under test. This invention also provides a pH sensing system comprising a separable and flexible pH sensor for measuring the pH value of a solution under test, wherein the transistor of the pH sensor can be prevented from direct contact with the solution.
