An all‐solid‐state impedance metric hydrogen‐phosphate ion sensor device has been tried to fabricate using BaTiO3 as a transducer and spinel‐type oxide receptor. AC impedance measurement was carried out using flow‐cell system with boric‐acid buffer solution with hydrogen‐phosphate ion The Co2RhO4/BaTiO3 sensor device was found to show impedance responses to hydrogen‐phosphate ion at 5 × 10−4 M and 1.0 × 10−2 M with the 90% response time of ca. 150 s. The Co2RhO4/BaTiO3 device showed good response characteristics among the tested devices in terms of sensitivity and restoration rate. © 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.
