1. An artificial bladder comprising:
a main body which includes an inlet port, an outlet port, an inner wall that forms a first reservoir portion configured to store urine between the inlet port and the outlet port and that is provided to be expandable and contractible, and an outer wall that forms a second reservoir portion configured to surround at least a partial region of the inner wall, the outer wall having a fluid port provided to introduce a fluid into the second reservoir portion or discharge the fluid from the second reservoir portion to the outside;
a sensor which is attached to the inner wall, has a surface having a wrinkled structure, and is provided so that, when a volume of the first reservoir portion increases, the wrinkled structure stretches out and resistance of the sensor changes;
a control unit which is provided to discharge the urine in the first reservoir portion through the outlet port according to a result detected by the sensor;
a fluid storage tank having a predetermined reservoir;
a fluid flow path configured to connect the fluid storage tank and the fluid port; and
a pump provided to allow the fluid to flow to the fluid flow path.
