wireless communication systems, networks based on presently disclosed metamaterial textiles are interconnected by radio-wave surface plasmons that propagate along structures patterned on clothing. These networks are not subject to inverse square law losses inherent to radiative transmission and require physical proximity to the body of the user in order to transmit and receive signals through interactions mediated by an evanescent field. Because clothing integrated with such metamaterials may be comprised entirely of fabric and may not involve active electronic components, they may be robust to daily wear and may be washed without any harm to the clothing or to its signal transmission capabilities. 

[0077] According to embodiments of the present disclosure, networks interconnected in this way enhance energy efficiency by many orders of magnitude and meet requirements for wireless power transfer, enabling distribution of power to batteryless sensors on the body of a user. 

[0078] Reference is now made to FIG. 1A, which is a schematic illustration of a sensor network interconnected by radio-waves confined on clothing. Devices in the network may exchange energy and information through the evanescent field of surface waves rather than radiation into the surrounding space. According to FIG. 1A, networks based on metamaterial textiles may be interconnected by radio-wave surface plasmons that propagate along structures patterned on clothing worn by a user. In some embodiments, the network may comprise a smart-clothing hub to enable connection of multiple devices or sensors along the network illustrated in FIG. 1A. 

[0079] Reference is now made to FIG. 1B, which is a schematic illustration of a structure of the metamaterial textile, according to embodiments of the present disclosure. According to some embodiments, the metamaterial textile is comprised of a sheet of metamaterial textile cut into a comb shape. The comb shaped metamaterial textile 110 may comprise a long base 120 with a plurality of teeth 122 extending along and from the base 120, wherein a gap, e.g., gap 124, is present between every two adjacent teeth 122. 

[0080] According to some embodiments, the comb shaped metamaterial textile 110 may comprise a non-conductive layer 112, e.g., clothing, attached to the comb shaped metamaterial textile 110. The non-conductive layer 112 typically being located beneath the comb shaped metamaterial textile 110. 

[0081] According to some embodiments, the comb shaped metamaterial textile 110 may further comprise a protective conductive layer 114 attached to and located beneath the non-conductive layer 

112. 

[0082] The configuration of the metamaterial textile of the present disclosure, comprising at least three layers of metamaterial shaped as a comb with teeth and gaps therebetween, at certain dimensions and distances from one another, and the addition of a non-conductive layer as well as a protective
