Heading element for charging devices

A charger, comprising:

• a substrate layer;
• an AC electrode layer coupled with said substrate layer;
• a dielectric layer coupled with said AC electrode layer;
• an aperture electrode layer coupled with said dielectric layer and electrically insulated by said dielectric layer from said AC electrode layer;
• and
• a heater coupled with said substrate layer on an opposite side from said AC electrode layer.

A heater for use in a charger, said heater comprising:

• a base;
• a first contact disposed on said base;
• a second contact disposed on said base;
• and
• a heating element coupling said first contact and said second contact, said heating element arranged in a non-uniform pattern such that an energy density of said heating element increases approximately exponentially from a first energy density at predetermined non-heat sink locations to a relatively higher second energy density at predetermined heat sink locations.
