Systems and methods for elastic wireless power transmission devices

A wireless power transfer system comprising:

• a wireless power receiver configured to be implanted within a subject;
• and
• a wireless power transmission device wearable by the subject, the wireless power transmission device configured to wirelessly transmit power to the wireless power receiver, the wireless power transmission device comprising:
• a power conditioner comprising a first end and an opposite second end;
• and
• a band comprising:
• a first end fixedly coupled to the power conditioner first end;
• a second end fixedly coupled to the power conditioner second end;
• a body extending between the band first end and the band second end, the body comprising at least one elastic segment;
• and
• a plurality of conductive wires extending along the body to form a plurality of conductive loops, at least one of the plurality of conductive wires electrically coupled to the power conditioner.
