BIOSENSOR CARTRIDGE AND BIOSENSOR SYSTEM INCLUDING SAME

A biosensor cartridge can include a circuit board including a connection terminal electrically connectable to an external diagnostic device; a sensor chip detecting a target material from an applied analysis specimen, having a reactant reacting specifically with the target material, and transmitting an electrical signal generated by reacting with the detected target material to the connection terminal of the circuit board; and a housing accommodating the circuit board and the sensor chip and surround the circuit board and the sensor chip so that the connection terminal is exposed. The housing has an inclined surface dent from an upper surface and forms an accommodating portion that exposes the sensor area of the sensor chip and accommodates the test specimen. Further, the accommodating portion includes a pattern structure for lowering surface energy.
