The present invention provides a polymer compound peeling agent usable for peeling as many types of polymer compounds as possible and capable of reducing a burden required for a peeling treatment when a polymer compound having adhered to an adhesion object is peeled. The polymer compound peeling agent for peeling a polymer compound having adhered to an adhesion object contains a photoresponsive liquid crystal material having a phase structure reversibly transitioning between an isotropic phase and a liquid crystal phase due to photoisomerization based on irradiation lights of different wavelengths. When the polymer compound is adhered to the adhesion object, the photoresponsive liquid crystal material is contained in the polymer compound with the phase structure set to the isotropic phase, and the phase structure of the photoresponsive liquid crystal material is allowed to transition from the isotropic phase to the liquid crystal phase by photoisomerization based on the light irradiation.

A gel nail for attaching to a fingernail of a user includes an elongated nail body having a root end, a tip end and two side edges, and defining an attachment portion at said root end for attaching on the fingernail and an extension portion at said tip end for being extended beyond the fingernail. A curvature at the root end is smaller than a curvature of the tip end, such that the root end is more flatten than the tip end. Each of the side edges has a reduced thickness to enable the attachment portion to be bent for matching with a curvature of the fingernail of the user.

A method of preparing a light-curable artificial nail includes extracting from an adhesive film in a semi-cured state a portion of the adhesive film in a shape of a human nail. The portion of the adhesive film includes a light-curable composition in the semi-cured state. A portion of the polish film in the shape of the human nail is extracted from a polish film. The portion of the adhesive film and the portion of the polish film are combined to form layers of the light-curable artificial nail.

An electronic false nail device includes an electronic ink false nail patch and a data transmission box. The electronic ink false nail patch includes a micro capsulation array layer and a circuit board. The micro capsulation array layer includes plural transparent shells, plural positively-charged first color particles and plural negatively-charged second color particles. These color particles are movable within the transparent shells. When the electronic ink false nail patch receives a signal from the data transmission box, plural positive electrodes and plural negative electrodes are generated by the circuit board. The positively-charged first color particles and the negatively-charged second color particles of each micro granule are moved to the corresponding positions according to the positive electrodes and the negative electrodes. Consequently, the micro capsulation array layer exhibits a predetermined pattern.

The present disclosure provides a nail-mounted tactile displaying device, including: a body; a plurality of vibration units provided at different positions of the body and actuated upon receiving a signal. The nail-mounted tactile displaying device provides a user with a new operating experience via the actuations of the plurality of vibration units so that the user can receive information through tactile feedback.

An artificial electronic nail made of a stack of thin layers, the stack having a shape of an artificial nail and including a first top thin layer having an electronic display facing upward, such that, when content is displayed by the electronic display, the content is visible from above the first top layer, a second thin layer having a contactless module having an antenna and being configured for contactless communication with a smart electronic device and a third thin layer having a central processing unit (CPU) connected to the contactless module and the electronic display and storing processor-executable instructions on a non-transitory processor-readable memory of the CPU that when executed by the CPU enables the artificial electronic nail to change its appearance and to perform various contactless communications with the smart electronic device.

An apparatus for applying a decal to a nail of a human digit is provided. A base coat of base nail polish is applied to a nail. The base coat has a tacky surface when dry. A decal application product is pressed against the tacky surface of the base coat, and includes a substrate and at least one decal adhered thereto. The decal and the substrate have a first adhesion coefficient therebetween. The decal and the tacky surface have a second adhesion coefficient that is greater than the first adhesion coefficient to cause a subset of the decal to adhere to the base coat. A top coat of a top nail polish is applied atop of the base coat and the subset of the decal to seal the subset of the decal and the base coat.
