## RADIO-WAVE CONFINEMENT ON METAMATERIAL TEXTILES FOR WIRELESS SENSOR NETWORKING 

## TECHNICAL FIELD 

[001] The present disclosure generally relates to radio-wave confinement on textile patterns for wireless sensor networking, and more specifically a system and method to confine radio-waves onto clothing patterned with conductive textiles (metamaterial textiles). 

## BACKGROUND 

[002] Over the past decade, rapid progress has been made in the development of sensors, displays, and smart devices that integrate seamlessly with the body. Wireless networks of sensors, displays, and smart devices on the body offer powerful capabilities for health monitoring, human-machine interfaces, and other emerging technological applications. 

[003] For instance, direct wiring between sensor nodes is widely used in clinical and research settings, but such approaches disrupt physical activity and are not compatible with continuous use. Recent advances in flexible electronics enable the integration of distributed sensors into clothing or onto skin, but do not address the interconnection of discrete devices. 

[004] Meanwhile, wireless networks of wearable devices have so far been limited by challenges in radiative loss, interference, and data security that are inherent to the use of radio-wave radiation into the surrounding space. Despite promising advances in advanced communication circuits and protocols, such wireless networks have not yet been widely adopted owing primarily to energy constraints and limited sensors lifetime. 

[005] There is therefore a need for systems and methods that enable efficient and secure transmission of wireless signals between devices worn on or implanted in a user’s body, such as sensors, medical implants, headphones, displays, and smart devices, or that enable transfer of power to devices around the body of the user.
