Wearable tag capable of wireless communications

A wearable tag capable of wireless communications includes a dry inlay layer having a lower surface, an upper surface, and a side surface, wherein the dry inlay layer is embedded with a semiconductor chip and an antenna circuit that are configured to wirelessly communicate with external devices. The wearable tag also includes an adhesive layer on the lower surface of the dry inlay layer. The adhesive layer is adapted to adhere to a human skin. An elastic layer on at least a portion of the upper surface of the dry inlay layer provides flexibility to the wearable tag.
