  • Patent number: 11724406
    Abstract: A pneumatic controlled soft gripper includes a chamber having a negative-pressure action space defined therein and having an opening communicating with the negative-pressure action space; a sucker extending radially outwardly from the opening of the chamber and having an annular contact surface; an expandable and contractible protuberance protruding from a top face of the negative-pressure action space opposite to the opening, wherein the protuberance is received in the negative-pressure action space, and has a gas pocket defined therein; and a gas channel extending from an outer face of the chamber into the gas pocket, wherein gas flows into and out of the gas pocket through the gas channel.

  • Patent number: 11530909
    Abstract: The present invention relates to a fiber composite for a strain sensor and a method for producing the same. The composite includes a stretchable fiber; a conductive elastic polymer layer coated on the stretchable fiber; polymer beads disposed on the stretchable fiber or on the elastic polymer layer; and a conductive elastic polymer layer covering the polymer beads. The fiber composite is durable and stable. Therefore, a strain sensor produced using the fiber composite exhibits excellent durability, recoverability, repeatability and sensitivity, and a fast sensing speed.

  • Patent number: 11058609
    Abstract: The present invention relates to an adhesive patch. The adhesive patch includes a plurality of reliefs, each relief having a flat top face, and each micro channel groove defined between adjacent reliefs of the plurality of reliefs, wherein the plurality of reliefs and the micro channel groove are respectively formed on and defined the adhesive patch, and wherein a hydrogel layer is disposed on at least a portion of a bottom face of the micro channel groove and is contained in the groove. Therefore, the adhesive patch is well-adhered to a dry or wet adhered face.

  • Publication number: 20110271497
    Abstract: Provided are a dry adhesive fastening system which has a relatively superior adhesion, does not almost generate noises during the attaching or detaching operation, has a simplified structure adapted to mass production requirements, and a method of using the same. For this, the dry adhesive fastening system includes a first adhesion member having a first microvillus disposed on a first board and a second adhesion member having a second microvillus disposed on a second board to contact the first adhesion, thereby providing adhesion. Also, unlike the existing velcro fastening system, the hook and loop may not be classified to improve production yield and effectiveness. Also, during the attachment/detachment, the noises may do not occur. In addition, since the microvillus having the micro or nano size is used, the adhesion may be realized even though a very small area is provided.
