A sensor and a method of manufacturing the same are provided. The sensor includes a substrate, a projecting portion including a plurality of projections that protrude upwardly from an upper portion of the substrate, and an electrode portion covering the projections and the upper portion of the substrate between the projections. The projecting portion of the sensor has micro projections to enable the sensor to sense pressure and a sliding movement.

Sensor and method of manufacturing the same

Provided herein is a phantom and a phantom system, the phantom including a plurality of blocks combined having different elastic modulus, and thus may be easily manufactured in various shapes, movements, and densities and may exactly imitate movements of a tissue such as in a lung that has high volume change rates and has a high possibility that a position and shape of a tumor may change, thereby providing an effect of being used in replacement of patients when evaluating 4D-CT performance and measuring radiation amounts.

Phantom and phantom system

A brake mechanism of a robot using a multi-output differential gear, capable of selectively blocking or applying driving force as needed, the brake mechanism including, a differential gear unit receiving driving force and generating at least three outputs differentiated from the driving force while being linked with the driving force, a driving unit transferring the driving force to the differential gear unit and moving in a direction away from or approaching the differential gear unit to thereby be detachably provided in the differential gear unit, and a rescuing unit controlling a spaced distance between the driving unit and the differential gear unit to attach and detach the driving unit to and from the differential gear unit.

Brake mechanism of robot using multi-output differential gear

Provided herein is a multi-axis sensor including: a pair of electrodes positioned such that at least partial areas thereof face each other; an elasticity member having one of the pair of electrodes installed in its upper portion and another of the pair of electrodes installed in a lower portion; and a sensor unit electrically connected with the pair of electrodes, and configured to detect a change of capacitance value between the pair of electrodes and a change of resistance value of the elasticity member.
