In this study, chitosan was blended with ferredoxin to further improve the electrical properties of sensing film. Chitosan powder was dissolved in 2% of acetic acidand blended with ferredoxin. The mixture was subsequently deposited on printed circuit board using electrochemical deposition technique to form films. Electrical testing of chitosan and chitosan-spinach films wasdone by exposing them to wet air and dry airusing air exposure technique. Electrical testing results showed that the output voltage increased with the addition offerredoxin. Scanning Electron Microscope (SEM) results showed that the surface of chitosan-ferredoxin film is smoother and more compact than chitosan film. Fourier Transform Infrared Spectroscopy (FTIR) results showed that there was N-H bonding and O-H bonding in chitosan film. Meanwhile, there was an extra peak in chitosan-ferredoxin film, which indicates the existence of [Fe-S] group.
