Modern Smart Phones
Many smart phone manufacturers have started adding this technology into their products. The majority of these phones have adopted the Qi wireless charging standard. Both manufactures, Apple and Samsung, produce many models of their phones in high volume with Qi capabilities. The adaption of the Qi standard has driven other manufacturers to adopt this as their own standard. Smartphones have become the driver for this technology entering consumers’ homes where many household technologies have been developed to utilize this tech. The current push for Qi technology is in consumer smart phones. As this tech is pushed to the consumers there have been many different ideas of what wireless charging will look like. Samsung and other companies have begun exploring the idea of surface charging. Meaning making their wireless chargers the entire surface such as a desk or a table. These chargers are large and work well for those people who work at a desk. Contrarily, Apple and Anker are pushing a dock based charging platform. This includes charging pads and disks that have a much smaller foot print. These solutions are geared for consumers who wish to have smaller chargers that would be located in common areas and could blend in with the current décor of their home. Due to the adoption of the Qi standard of wireless charging any of these charger will work with any phone as long as the phone is Qi capable.

Future Technology
Work and experimentation is currently underway in designing this technology to be applied to electric vehicles. This will be implemented by using a predefined path or conductors that would transfer power across an air gap and charge the vehicle on a predefined path such as a wireless charging lane. Vehicles are already on the road that could take advantage of this type of wireless charging lane to extend the range of their on board batteries. Some of the issues that are currently preventing these lanes from becoming widespread is the initial cost associated with installing this infrastructure that would only benefit a small percentage of vehicles currently on the road. Another complication is tracking how much power each vehicle was consuming/pulling from the lane. Without a commercially way to monetize this technology many cities have already turned down plans to include this lanes in their public works spending packages. However this doesn’t mean that cars are unable to utilize large scale wireless charging. The first commercial steps are already being taken with wireless mats that allow electric vehicles to be charged without a corded connection while parked on a charging mat. These large scale projects have come with some issues which include the production of large amounts of heat between the two charging surfaces and may cause a safety issue. Currently companies are designing new heat dispersion methods to combat this excess heat this includes most major electric vehicle manufactures such as Tesla, Toyota, and BMW.

Medical Implications
Wireless charging is making an impact in the medical sector by means of being able to charge implants and sensors long term that are located beneath the skin. Researchers have been able to print wireless power transmitting antenna on flexible materials that could be place under the skin of patients. This could mean that under skin devices that could monitor the patient status could have a longer term life and provide long observation or monitoring periods that could lead to better diagnosis from doctors. These devises may also make charging devices like pacemakers easier on the patient rather than having an exposed portion of the device pushing through the skin to allow corded charging this technology would allow a completely implanted device making it safer for the patient. It is unclear if this technology will be approved for use more research is needed on the safety of this devices. While these flexible polymers are safer than ridged sets of diodes they can be more susceptible to tearing during either placement or removal do to the fragile nature of the antenna that is printed on the plastic material. While these medical based application seems very specific the high speed power transfer that is achieved with these flexible antenna is being looked at for larger broader applications.
