Biosensor cartridge and biosensor system including same

A biosensor cartridge including a connection terminal exposed at a side, the connection terminal outputting an electronic detection signal generated according to a detected target material from an applied analysis specimen;

• and
• a diagnostic device including:
• a display device;
• and
• an insertion hole to which the connection terminal the biosensor cartridge is inserted,
• wherein the diagnostic device is configured to analyze the electronic detection signal from the biosensor cartridge, determine a concentration the detected target material and display the concentration the detected target material on the display device,
• wherein the biosensor cartridge includes;
• a sensor chip including a sensor area reacting with the detected target material;
• a circuit substrate connected to the sensor chip and formed with the connection terminal at an end thereof;
• and
• a housing for accommodating the circuit substrate and the sensor chip,
• wherein the housing includes an accommodating portion for accommodating the analysis specimen,
• wherein the accommodating portion has an inclined surface on which the analysis specimen flows, and exposes the sensor area the sensor chip, and
• wherein the inclined surface the accommodating portion includes a plurality of pattern grooves configured to create a contact angle between the analysis specimen and the plurality of pattern grooves which is 100 degrees or greater for lowering a surface energy the analysis specimen,
• and wherein the plurality of pattern grooves includes a pattern groove and a pattern protrusion, a width the pattern groove being 1.5 to 4.5 times a width the pattern protrusion.
