The inventive concept relates to a wearable hand robot mounted on a finger to bend the finger by an external force transmitted through a wire. The wearable hand robot is capable of preventing an injury to a user's hand by the wire, achieving simplification of the structure of a finger cap and an improvement in a wearing sensation, and stably moving the finger while having a tactile sensation.

The present invention provides an active clutch mechanism and a hopping robot equipped with the same, the active clutch mechanism comprising: a sun gear; a planetary gear; and a winding gear. When the sun gear rotates in one direction, the planetary gear revolves around the sun gear in the one direction to come into contact with the winding gear, and then rotates the winding gear to wind a wire so as to store energy in an energy storage unit connected to the winding gear. When the sun gear rotates in a direction opposite to the one direction, the planetary gear revolves around the sun gear in the direction different from the one direction to become spaced from the winding gear, so as to discharge the energy stored in the energy storage unit.

An acupressure device includes an acupressure section, a driving part and a control part. The acupressure section is disposed in front of the belly and presses the belly. The driving part is connected to the acupressure section and fixed at a backside of a user and moving the acupressure section toward the belly. The control part is controlled by the user and changing an intensity of a pressure from the acupressure section.

Disclosed herein is a deformation sensing flexible substrate using a pattern formed of a conductive material. The deformation sensing flexible substrate, using the pattern formed of the conductive material, includes a flexible substrate; and conductive patterns in which conductors including a conductive material are arranged and formed to be contactable and non-contact to each other based on deformation of the flexible substrate.

The pen holder includes a first, second and third cover portions, a connecting part and a fixing unit. The first, second and third cover portions are respectively inserted into a thumb, a forefinger and a middle finger. The connecting part connects the first, second and third cover portions. A first end of the connecting part is fixed to one of the first, second and third cover portions. A force is applied to a second end of the connecting part such that the first, second and third cover portions are closed to each other. A fixing unit fixes to the second end of the connecting part and applies the force to the connecting part.
