New wireless charging method allows for deep body implants

A new report details the work of a Stanford researcher who has developed a method for charging deeply-implanted micro-electronics in the body, something that henceforth hasn't been possible due to charging restrictions. With this, the increased use of implants to treat disorders becomes more feasible.

The method is called mid-field wireless transfer, and allows for small implants that can be deeply embedded in the body or brain. One example already created is a pacemaker said to be smaller than a grain of rice, able to be charged with a power source about the size of a credit card.

The research team was led by Stanford electrical engineering assistant professor Ada Poon, who says making the implants smaller will ultimately result in new treatment options for pain and disorders. Drug delivery, stimulation, and other functions are all possible with the implants.

The wireless charging method is akin to the method used to charge gadgets, but is able to reach deeply-implanted devices unlike common near-field waves. Human trials are set to take place in the near future, but it'll be a while before the technology is common place.
