Abstract

The present invention relates to a sensor used together with a detector to measure biomaterial, and to an apparatus using same. A sensor of the present invention comprises: a body portion with a three-dimensional shape, having a biomaterial introduction hole, and attachable and detachable to/from a detector; a sensor portion with a plurality of reaction electrodes formed on one surface thereof, and a plurality of transfer electrodes formed on the other surface thereof; and an analyzer reagent fixed above the reaction electrodes. The sensor portion, together with the body portion, forms a reaction chamber connected to the biomaterial introduction hole, and is attached to the body portion such that the reaction electrodes are oriented toward the reaction chamber. According to the present invention, attachment and detachment is easy, even for the elderly, and the contamination of the sensor can be minimized.
