DETAILED DESCRIPTION

Reference will now be made in detail to the preferred embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. While the disclosure will be described in conjunction with the preferred embodiments, it will be understood that they are not intended to limit the disclosure to these embodiments. On the contrary, the disclosure is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the disclosure as defined by the claims. Furthermore, in the detailed description of the present disclosure, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be obvious to one of ordinary skill in the art that the present disclosure may be practiced without these specific details. In other instances, well known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure embodiments of the present disclosure.

Wearable devices may have a plenty of health benefits, but they may also cause skin irritation for some. To securely wear wearable devices, such as smart watches, bracelets or rings, to the skin of the user, elastomer, stainless steel, leather, fabric and/or some other material may be employed. However, one may notice dry, potentially itchy red splotches around the devices on your wrists or fingers once you start to use the devices consistently. For instance, one may experience an allergy to one or more materials present in the wrist band for smart watch, which are often made of rubber silicone because silicone traps more moisture. On the other hand, bands made of cotton and silk may allow sweat to escape naturally from the skin of the user, but such bands may be exposed to a wear and tear problem.

To deal with those issues, embodiments of the present disclosure propose a band system made of a hybrid band comprising a fabric layer and an elastomer layer, a watch comprising such band system and a hybrid band for wearable devices. The hybrid band for band system, watch and wearable devices is implemented to reduce the skin problem caused by the conventional band system while resistant to the wear and tear of the conventional band system.

FIGS. 1A and 1B illustrate a top view and a bottom view of a band system 100 for securing a watch to a user according to an embodiment of the present disclosure. In one embodiment, the band system 100 for securing the watch to the user comprises a buckle side band 102 which includes a buckle 104 and a keeper 106.

In one embodiment, each one of the buckle side band 102 and the point side band 108 of the band system 100 is made of a hybrid band. The hybrid band is made by securely adhering or fixedly attaching an elastomer layer 112 with a fabric layer 114. Accordingly, when the watch is worn by the user, the fabric layer 114 of the hybrid band faces a wrist of the user, thus substantially touching a skin of the user, whereas the elastomer layer 112 of the hybrid band is physically separated from the wrist or skin of the user by the fabric layer 114.

In one embodiment, the fabric layer 114 is made of nylon. Alternatively, the fabric layer 114 is made of one or more of linen, silk, cotton, polyester, hemp, leather, satin, wool, chiffon, crepe, georgette, muslin, rayon, velvet, canvas, damask, denim, elastane, lace and jersey. In another embodiment, the fabric layer 114 is based on a sportswear which is commonly made from a variety of materials and blends, such as polyester, nylon and spandex, where these synthetic fibers are lightweight, durable and/or breathable. To generate and/or enhance the qualities of the sportswear, the fabric layer 114 comprises a voluminous surface.

In one embodiment, the elastomer layer 112 is made of silicone. Alternatively, the elastomer layer 112 is made of thermoplastic polyurethane. Alternatively, the elastomer layer 112 may be any polymer that has viscosity and elasticity and therefore is known as viscoelasticity, where the molecules of the elastomer layer 112 are held together by weak intermolecular forces and generally exhibit low Young's modulus and high yield strength or high failure strain. Examples of the elastomer layer 112 include natural rubbers, styrene-butadiene block copolymers, polyisoprene, polybutadiene, ethylene propylene rubber, ethylene propylene diene rubber, silicone elastomers, fluoroelastomers, polyurethane elastomers, and nitrite rubbers.
