Abstract: Methods, systems, and devices for an apparatus that performs near field communications are described. A near ultra low energy field (NULEF) system may be used in systems that come in close contact with the human body. NULEF-E may experience limited performance due to external electric fields generated by a human body. NULEF-E may also be used across other bodies having electrically conductive or semi-conductive surfaces. The interference of the external electric fields may be mitigated by increasing the electrical length between a transducer and an electrode of the system. In particular, a wire electrically connecting a transceiver and a electrode may have a wire length that is also an electrical length between the transceiver and the electrode, the wire being configured such that a physical distance between the electrode and the transceiver is less than the wire length while maintaining the electrical length.
