A smart screw according to an embodiment may comprise: a screw main body which penetrates an artificial joint including a shell disposed on a hip joint of an object and a liner disposed on the inner surface of the shell and is then inserted into the hip joint; a transducer including a coupling layer that senses a sound wave signal reflected from the liner, a piezo-electric layer formed to determine a frequency of the sound wave signal, and a sound absorbing layer for absorbing the sound wave signal; and a processing module for generating a sound wave signal toward the liner and receiving the sound wave signal sensed by the coupling layer, measuring the thickness of the liner on the basis of the received sound wave signal, and transferring data about the measured thickness of the liner to the outside.

Smart screw

Disclosed is a position indicating apparatus including a main body, a first arm connected to one side of the main body based on a symmetric axis of the main body, a second arm connected to another side of the main body based on the symmetric axis, a first light radiator connected to one end of the first arm to radiate a light, and a second light radiator connected to one end of the second arm to radiate a light, wherein the light radiated from the first light radiator and the light radiated from the second light radiator meet and form an intersection of line.

Position indicating apparatus and bone fixation apparatus including the same

Provided are a phase-change memory device using insulating nanoparticles, a flexible phase-change memory device and a method for manufacturing the same. The phase-change memory device includes an electrode, and a phase-change layer in which a phase change occurs depending on heat generated from the electrode, wherein insulating nanoparticles formed from a self-assembled block copolymer are provided between the electrode and the phase-change layer undergoing crystallization and amorphization.
