Abstract
A sensor array device includes a substrate and electrodes. The electrodes include a power electrode located in a first region of the substrate and a plurality of working electrodes located in a second region of the substrate. Surfaces of the working electrodes have various specific enzymes, respectively, and the specific enzymes on the surfaces of the working electrodes are different. The plurality of working electrodes are located in different sub-regions of the second region, respectively. The sensor array device further includes a guide layer or a hydrophilic layer. The guide layer is located above the electrodes and covers the first region and the second region. An edge of the guide layer extends to an edge of the substrate. The hydrophilic layer is arranged on the substrate and covers the first region and the second region, and an edge of the hydrophilic layer extends to the edge of the substrate.
