An artificial bladder is provided, including: 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 expandable and contractible. An outer wall forms a second reservoir portion configured to surround at least a partial region of the inner wall. A sensor is attached to the inner wall, has a surface having a wrinkled structure, and is provided so that, when the volume of the first reservoir portion increases, the wrinkled structure stretches out and resistance of the sensor changes. A control unit is provided to discharge the urine in the first reservoir portion through the outlet port according to a result detected by the sensor.

Biomimetic artificial bladder and method for controlling same

A method of fabricating a polymer wire according to the present embodiment includes preparing an electrode platform having a micro gap, forming a plurality of single polymer wires on the electrode platform, and a heat treatment operation of aggregating the plurality of single polymer wires to form an aggregated polymer wire.

Method of fabricating suspended nanowire using heat treatment

Provided is an artificial bladder including: a main body which includes an inlet port, an outlet port, and a predetermined reservoir portion configured to store urine between the inlet port and the outlet port and is formed of a biocompatible polymer that is expandable so that a volume of the reservoir portion changes according to the amount of urine; a sensor which is attached to an outer wall of the main body, has a surface having a wrinkled structure, and is provided so that, when the volume of the reservoir portion increases, the wrinkled structure stretches out and resistance of the sensor changes; and an actuator which is provided at the outlet port and is configured to discharge the urine according a result detected by the sensor.
