Abstract
An electronic device includes a substrate and a plurality of sensors. Each sensor is disposed in a well over the substrate and includes a working electrode, an inner filling solution disposed thereover, and an ion-selective membrane. The working electrode is in contact with the substrate and the ion-selective membrane is disposed over the inner filling solution and substantially seals the well.
