Electronic skin tattoos with advanced near-field communication capabilities

(Nanowerk News) Researchers have demonstrated materials, mechanics designs and integration strategies for near field communication (NFC) enabled electronics with ultrathin construction, ultralow modulus, and ability to accommodate large strain deformation.
These attributes allow seamless, conformal contact with the skin and simultaneous capabilities for wireless interfaces to any standard, NFC enabled smartphone, even under extreme deformations and after/during normal daily activities.

As the researchers reported in Small ("Epidermal Electronics with Advanced Capabilities in Near-Field Communication"), detailed experimental studies and theoretical modeling of the coupled mechanical and electromagnetic responses of these systems establish foundational understanding of their behavior. These materials and device architectures have potential for utility in other types of radio frequency (RF) electronic systems and for use on other organs of the body.
The materials, device designs and integration strategies introduced in this paper enable state of the art NFC technology to be integrated in a seamless manner with the surface of the skin. The combined considerations in materials, electromagnetic and mechanical properties are essential to robust, functional operation and effective, skin-like properties.
The same concepts should be applicable to other types of RF electronic systems and other organs of the body.
