A wearable antenna is described, for wirelessly receiving sensor data generated by an implantable sensor device implanted in a uterus, the wearable antenna, in use, extending around the waist of the wearer's body, and having a downwardly extending portion for location at the front of the wearer's body. In this way, an improved electromagnetic interaction between the wearable antenna and the implantable sensor can be achieved. Further, the wearable antenna may have an undulating shape around at least a portion of the wearer's waist, to permit expansion and contraction of the wearable antenna about the wearer's waist.

A “core” or “inlay” for a smartcard may comprise a first metal layer and a second metal layer, and may be formed by folding a single metal layer upon itself. A module cavity may be formed in the first metal layer by laser cutting, prior to laminating. An adhesive layer may be disposed between the two metal layers. A module opening may be formed in the second metal layer by milling, after laminating the first metal layer to the second metal layer. A slit in a metal layer may extend from an outer edge of the layer to the cavity or opening, thereby forming a coupling frame. The slit may have a termination hole at either end or at both ends of the slit. The slits of two metal layers may be positioned differently than one another.

An electronic device and method for controlling the electronic device are provided. The electronic device includes a first surface in a first direction, a second surface in a second direction opposite to the first direction, and a third surface enclosing at least a portion of a space formed between the first surface and the second surface. The electronic device also includes an audio module changing an audio signal input to the electronic device into an electronic signal, and a processor being operationally connected to the display and the audio module. The processor is configured to detect the audio signal input via the audio module from a first user via the first surface, detect a touch signal dragged from the third surface in the direction of the second surface, and display in the second surface a translation corresponding to the audio signal.
