The novelty in this invention, rather than being about the liquid metal materials themselves, is around the use of liquid metals as antennas in a stretchable substrate (e.g., the metal could be injected into a silicone band or used as a conductive core of a thread for a textile band). The use of liquid metals as antennas in wearables could be the best way to significantly increase antenna surface area without introducing problematic points of failure, as liquid metals are self-healing (e.g., to minor puncture damage) and highly adaptable. This concept could be used in any wearable strap and may be particularly useful in watches.
