A charge coupled device (CCD)-type multi-ion image sensor for sodium ion and potassium ion was fabricated. Two kinds of plasticized poly(vinyl chloride) (PVC) membranes contained different ionophores were separately prepared on the semiconductor image sensor. The membrane preparations were occurred by a conventional casting method with hand painting, and inkjet painting with a laboratory inkjet printing apparatus. Since the casting solvent of tetrahydrofuran (THF) has low viscosity and high osmosis, a pre-constructing PVC membrane was...
