Biosensor
First Claim
1. A biosensor that is configured to be inserted into a display device and measures a material contained in a sample, the biosensor comprising:
- first and second substrates that are opposed to each other and comprise a long edge, and a short edge that shares a corner of the biosensor and neighbors the long edge;
a sample guiding layer;
a penetrated opening that penetrates the first substrate, the sample guiding layer, and the second substrate;
a first electrode that is located between the first substrate and the sample guiding layer;
a second electrode that is located between the first substrate and the sample guiding layer, and spaced apart from the first electrode;
a third electrode that is located between the sample guiding layer and the second substrate;
a fourth electrode that is located on the first substrate wherein the fourth electrode is located closer to the display device than the first electrode when the biosensor is inserted into the display device;
wherein the sample guiding layer has two sample inlets and is located on the first substrate, wherein each of the two sample inlets correspond to the long edge and short edge, respectively, and the sample inlet corresponding to the long edge is located closer to the fourth electrode than the penetrated opening;
wherein first and second sample guiding channels connect the two sample inlets, wherein the first and second guiding channels are connected to the penetrated opening at both sides of the penetrated opening opposite to each other; and
wherein the first guiding channel connects the sample inlet that corresponds to the short edge with the penetrated opening and the second guiding channel is bent and connects the sample inlet that corresponds to the long edge with the penetrated opening.

Abstract
A biosensor that is capable of measuring a material contained in a sample is provided. The biosensor is configured to be inserted into a display device, and measures a material contained in the sample. The biosensor includes i) first and second substrates that are opposed to each other; ii) a sample guiding layer that has two sample injection openings and is located on the first substrate; iii) a first electrode that is located between the first substrate and the sample guiding layer; iv) a second electrode that is located between the second substrate and the sample guiding layer; v) a third electrode that is located between the sample guiding layer and the second substrate; and vi) a penetrated opening that penetrates the first substrate, the sample guiding layer, and the second substrate. The second electrode is spaced apart from the first electrode. The biosensor further includes i) a long edge, and ii) a short edge that shares a corner of the biosensor and neighbors the long edge. Each of the two sample injection openings is formed to correspond to the long edge and the short edge, respectively.
