Artificial bladder system having dual space divided by partition and wireless, non-powered urine fullness sensor using RFID technology

An artificial bladder system comprising:

• an outer wall that forms an outer shape of the artificial bladder, is configured to be inserted into a body, and the outer wall has an inner space;
• a partition wall, wherein both ends are fixed to an inside of the outer wall, the inner space of the outer wall is divided into a double space of a urine reservoir and a working fluid space, and the partition wall is deformable according to amounts of an urine and a working fluid;
• and
• a urine fullness sensor installed in the working fluid space and sensing a urine fullness degree based on a deformation of the partition wall
• wherein the urine fullness sensor is a capacitive type sensor based on capacitance changes,
• wherein the capacitive type sensor comprises a capacitor composed of a first electrode and a second electrode,
• wherein the first electrode is configured in the form of a flat plate buried and fixed to an inner surface of the outer wall;
• and the second electrode is configured in a curved shape in which a first end of the second electrode is fixed to the first electrode, and a remaining part of the second electrode except the first end is separated from the first electrode, but the distance from the first electrode is gradually widened toward a second end opposite to the first end of the second electrode.
