Abstract: An array sensing electrode includes an electric insulating base plate, a plurality of electric conductive assemblies, a reference sensing layer, at least a chemical sensing layer, and an electrolyte layer. The electric insulating base plate has a plurality of perforations. Each electric conductive assembly includes an electric conductive filler, a first electric conductive part, and a second electric conductive part. The electric conductive filler is penetrated through the perforation, and the first electric conductive part and the second electric conductive part are disposed on a first plane and a second plane of the electric conductive filler, respectively. The reference sensing layer and the chemical sensing layer are disposed on different first electric conductive parts, and the electrolyte layer is disposed on the reference sensing layer and the chemical sensing layer to cover thereon. Therefore, the advantages of decreasing the manufacture cost and being conductive to packaging are achieved.

Abstract: A movable light-guiding device includes a light-guiding unit and at least one sucker unit. The light-guiding unit includes at least one light-guiding structure. The sucker unit is installed on the light-guiding unit. Accordingly, a user can easily make the light-guiding device adhere to an object or remove it from an object by using the sucker unit. The movable light-guiding device can be repeatedly installed and uninstalled and thereby it can improve the performance and user's convenience.
