Disclosed is wristband and wrist wearable device, including: a wristband body portion, one end is connected to one end of a device body of a wrist wearable device, and the other end is a free end; and a memory metal portion, which is arranged on the wristband body portion and has an arc-shaped memory state in a natural state, so that the wristband body portion is naturally maintained in an arc shape. The memory metal portion comprises a strip-shaped memory metal piece including a first metal segment, a second metal segment, and a third metal segment that are sequentially connected, the first metal segment and the third metal segment extend along a length direction of the wristband body portion in parallel, the second metal segment is arranged at the free end of the wristband body portion and is provided with at least one bent portion.

The present invention relates to a spring element having two bistable flat springs and two flat connecting elements which are arranged at the longitudinal ends of the bistable flat springs, which are aligned parallel to one another, and connect them to one another.

The present invention relates to a wrist encircling folding bracelet comprising a strap and a body connected to the band (2), with a first end module comprising at least two rigid arcuate elements, a reversibly deformable part comprising a multi stable element, the multi stable element assuming a stabilized shape both in a linear orientation and in a rolled-up orientation, and a second rigid module on which the band is arranged, comprising a multi stable element, said multi stable element assuming a stabilized shape both in a linear orientation and in a coiled orientation, and a second rigid module on which said strap is arranged, said strap being freely oscillating with respect to said body.

A dynamically flexible article or device, such as a wristband, an armband, a rollable e-reader, or a belt, includes a flexible electronic component (e.g., a flexible display) and a support structure coupled to the flexible electronic component. The support structure is configured to limit bending of the flexible electronic component to a range within a bending tolerance of the flexible electronic component.

The present invention relates to a mobile electronics device (10) to be fastened to a human body part (200), comprising an electronics housing (20) having electronics components (30) situated therein, wherein a flexible fastening arm (40) is situated in each case on the electronics housing (20) on two oppositely oriented wall portions (22), which fastening arms extend away from the electronics housing (20) and are flexibly deformable between a fastening position (FP), fastened to the body part (200), and a release position (RP), releasing the body part (200), and wherein, in the release position (RP), the fastening arms (40) are preloaded towards the fastening position (FP) with a preloading force (PF).

A decorated strip of coated, heat-shrinkable, plastic sheet material is placed in a spiral slot formed in a silicone rubber mold. The spiral slot is defined by a spiral wall having a uniform wall thickness. Upon heating in an oven, the material shrinks, forming a resiliently expansible arc-shaped band that can be worn as a bracelet or wristband.

A jewelry item has a closure that uses shape memory to provide two stable positions. For example, an earring has a setting and a pin, and the closure closes the pin over the ear. The closure consists of a leaf spring extending outwardly in a first loop part from a first location on the setting and looping back in a second loop part to a second location adjacent the first location on the setting. The loop parts each have shape memory and are set with different remembered shapes. The two different remembered shapes work against each other to flip the closure between two stable positions, a first position in which the closure connects to the pin to close the earring and a second position in which the closure is spaced away from the pin to open the earring. The design is particularly suitable for a huggie style earring.
