Biosensor cartridges and biosensor system having the same

A biosensor cartridge comprising:

• a circuit board including a connection terminal configured to be electrically connectable to an external diagnostic device and a plurality of connection pads electrically connected to the connection terminal;
• a sensor chip including a reactant, a plurality of electrodes, and a plurality of electrode pads electrically connected to the plurality of electrodes, the sensor chip being configured to:
• detect a target material from an applied analysis specimen, and
• transmit an electrical signal generated by reacting with the detected target material to the connection terminal of the circuit board;
• a plurality of connecting members electrically connecting the plurality of connection pads and the plurality of electrode pads;
• and
• a housing including a lower housing and an upper housing facing the lower housing and forming a space accommodating the circuit board and the sensor chip, the housing including an accommodating portion configured to accommodate the applied analysis specimen and expose the sensor chip to the applied analysis specimen,
• wherein the connection terminal is exposed outside the housing,
• wherein each of the plurality of connection members comprises:
• a first surface in contact with one of the plurality of connection pads;
• a second surface in contact with one of the plurality of electrode pads;
• and
• a bending portion extending between the first surface and the second surface and formed to be bent, and
• wherein the bending portion is elastically deformed by a pressure applied due to coupling of the upper housing and the lower housing.
