Abstract
Disclosed are a flexible pH sensor and detection system, belonging to the technical field of sensors. A material that does not react with electrolyte is mixed with metals to print an anode substrate, and one-step synthesis of a metal ions doped polyaniline composite material is realized through an electrochemical method. The doping amount of metal ions in polyaniline is changed by controlling metal content; due to addition of the metals, the conductivity of the anode substrate is improved, which is conducive to the deposition of polyaniline; such one-step method for preparing the polyaniline composite material is simpler, low in cost, and pollution-free; and compared with pure polyaniline, the sensitivity is further improved. According to the solution, this material is applied to the pH sensor for the first time, achieving a wide pH detection range (2-12) and high bending stability.
