The disclosure provides a smart jewelry device including a metal housing, two charging contacts, an insulating member, and a battery. The metal housing has a hollow portion, and the metal housing is axisymmetric relative to an axis. The two charging contacts are located on the axis and are respectively located at two endpoints of the metal housing. The insulating member is disposed among the metal housing and the charging contacts. The battery is disposed within the hollow portion and is electrically connected to the charging contacts.

Disclosed is a luminous necklace structure. The present invention adopts the following technical solution: A luminous necklace structure, comprising a battery case; a chain rope with both ends connected with the battery case; at least one pendant connected with the chain rope; so that the battery case can supply power to the chain rope and make the pendant luminous. The chain rope comprises two conductive wires which are fixedly connected in parallel. The battery case comprises a casing and a power supply assembly provided in the casing, with two ends of the two conductive wires connected to the casing and the conductive wires electrically connected to the power supply assembly.

Functional jewelry is disclosed. A bracelet includes a plurality of light-emitting diodes (LEDs), a main control unit, and positional and situational sensors, typically including an accelerometer, as well as a decorative, interchangeable fascial layer. The bracelet may also include sensors such as capacitive touch sensors, a microphone, and a color sensor. A radio transceiver within the bracelet is adapted to implement a protocol such as BLUETOOTH 4.0, and is adapted to allow the bracelet to communicate in peer-to-peer or master-slave mode. Two users can pair their bracelets in person, usually with a gestural trigger, for shared light displays, multi-player games, and other types of interactions. Larger groups can pair temporarily and contextually for multi-user displays and interactions, in an ad hoc network with distributed functions. Real-world interactions are communicated to a social network with profiles linked to the individual bracelets.

A powered light-up bead and assembly for use in jewelry items. The assembly forming a bracelet that can be adapted to several alternate types, embodiments, and styles of jewelry, including, but not limited to, necklaces, bracelets, anklets, and other similar ring or hoop-like assemblies having a length and a clasp for the coupling of a pair of opposed ends around a circumference. The assembly is configured for illumination from an interior space or cavity of a bead and having a resilient connecting portion between adjacent beads.

A motion activated illuminated bracelet includes a circular shaped main body having an inside diameter that is suitable for being worn about the wrist of a user. A plurality of illuminating charms is positioned equidistantly along the main body and include a power source, a switch and a light. A plurality of audible charms is positioned equidistantly along the main body and include a power source, a switch and a speaker. A plurality of decorative charms is positioned equidistantly along the main body and include a housing having any number of decorative elements, and a weight that is complementary to the weight of an audible charm or an illuminating charm. Each of the illuminating charms and the audible charms are selectively activated by a centrifugal force associated with the rotation of the bracelet, and some of the illuminated charms are connected to the main body via a resilient tether.

A bracelet or flexible band comprised of a flexible member that on one end is interconnected to a knife and on another end, is connected to a sheath that selectively receives the knife in the locking fashion. When needed, the knife is rotated within the sheath to facilitate release thereof from a lock that is integral with the sheath. Once removed from the sheath, the knife can be used for self-defense, cutting rope or cord in an emergency situation, or for general utility cutting tasks.

A lighting rope for an accessory includes a power control unit, a rope sleeve, and a flexible printed circuit board provided inside and extending along the rope sleeve. The flexible printed circuit board is sleeved with the rope sleeve by using a heat shrinkable film wrapping process. The flexible printed circuit board is provided in a length direction with a plurality of light-emitting diodes (LEDs) arranged at intervals. The power supply control unit includes a push button and a power supply battery. The LEDs are powered by the power supply battery and controlled by the push button to emit light. A semiconductor process is used to mount the LEDs on the flexible printed circuit board and the heat shrinkable film wrapping process is used to wrap the rope sleeve outside the flexible printed circuit board, greatly reducing the diameter of the existing lighting rope.

A wearable may be provided with or configured to provide interactive skin. The interactive skin may be configured for accepting touch input from a user. The interactive skin may include one or more flexible layers and may include or be mounted under a transparent display cover layer such as a layer of clear glass or plastic. Interactive skin may include a touch-sensitive layer that allows a user to provide touch input to the wearable. Display pixels on interactive skin may be used to display visual information to the user. The interactive skin may be configured for detecting a condition of at least one wearable and generating an output function in response to the detected condition.

Methods, systems, and devices for operating a wearable device are described. The wearable device may include a flexible inner body in the form of an open-ended ring that includes a first end that is movable relative to a second end such that an inner circumference of the inner body is expandable. The wearable device may include a flexible circuit board disposed concentrically around an outer circumference of the inner body and in the form of an open-ended ring. And the wearable device may include a flexible outer clip disposed concentrically around the flexible circuit board and in the form of an open-ended ring. The outer clip may be configured to provide a compressive force on the flexible circuit board and the outer circumference of the inner body.
