Upon the addition of water, the battery creates a radial electric field. (Note that this is not a skin-or sweat-powered energy-harvesting arrangement.) Their approach is in sharp contact with ...

The answer lies in the fact that on the nanoscale, optical fields are almost purely electric oscillations at ... inside the material within a certain skin depth and most of the incident radiation ...

The therapy is administered via a noninvasive portable device that delivers continuous electric fields to the patient through transducer arrays placed on the skin in the region of the tumor ( Fig.
