The present invention is directed to the production of shipping containers, computer server farm containers, and other forms of physical storage containers from a carbon nanotube-based fiber material with the potential application of other, non-carbon, nano-based materials containing various structures. Current materials used for shipping containers, computer server farm containers, and other forms of physical storage containers are heavier than the present invention and lack the ability to withstand high-intensity shock vibrations and other disturbances and are vulnerable to radiofrequency (RF) radiation. Instead of using metal, which is the currently preferred material used in the development of shipping containers, computer server farm containers, and other forms of physical storage containers, the present invention provides the use of a carbon nanotube-based material.

This disclosure provides systems and methods relating to medical devices that utilize dynamically tunable antennas comprising a plurality of sub-wavelength antenna elements. In various embodiments, impedance elements associated with the sub-wavelength antenna elements are dynamically tuned to control radiation patterns of a tunable antenna, such as a metamaterial surface antenna technology (MSA-T) antenna. The radiation patterns produced by the tunable antenna are used, for example, for sending a control signal to an implanted medical device, directly controlling the movement of a medical device, causing a medical device to perform a specific function, powering a medical device, and/or otherwise interacting a medical device. In some embodiments, the implanted medical device may also include an antenna, such as an MSA-T antenna, for receiving and/or sending beam-formed electromagnetic radiation.
