In this study, we propose a facile fabrication process for all-solid-state ion-selective electrodes by laminating and drop-casting; these electrodes are suitable for applications in the environmental, agricultural, and medical fields, such as oral condition monitoring. To date, research has focused only on developing ion-selective electrodes for specific applications. However, an ion-selective electrode with compatibility for wide use has not been realized because specialized processing techniques and equipment are required. Our fabrication process achieved an ion-selective multi-sensor with a wireless system, which is crucial for overcoming the aforementioned challenge. The developed sensors exhibited sufficient sensitivity, repeatability, response time, and selectivity for medical, environmental, and agricultural applications.
