1. A skin patch being:
for releasable attachment to a skin location of a patient,
the skin patch comprising:
a housing comprising a base for supracutaneous attachment to the skin location and a cover covering the base;
at least one ferromagnetic element for subcutaneous implantation below the skin location;
at least one magnet to position the skin patch at the skin location by magnetic coupling with the at least one ferromagnetic element, the at least one magnet being in the housing and affixed to the base and defining an aperture therewithin;
at least one electrode for sensing a body parameter and/or for affecting a body parameter, the at least one electrode being on the base and located in the aperture of the at least one magnet;
an antenna coupled to the at least one electrode and to receive wireless power transmissions for powering the skin patch;
additional magnets at opposing ends along a longitudinal axis of the housing, adjacent to the at least one magnet, and to align the skin patch to the skin location, the additional magnets being strip shaped in a direction crossing the longitudinal axis of the housing;
additional ferromagnetic elements for subcutaneous implantation below the skin location and to position the skin patch at the skin location by magnetic coupling with the additional magnets, the additional ferromagnetic elements being strip shaped to correspond to the additional magnets,
wherein the antenna comprises a radio frequency (RF) coil.
