Emergency Beacon with Scrunchable Antenna Can be Sewn into Clothes

lost may be getting harder to do with this new scrunchable, stretchable and water-resistant
antenna that can be sewn into your clothes:

It’s meant for life vests worn in the water, and connects
to the Cospas-Sarsat distress signal network. The Cold War-era system
consists of radio beacons on aircraft, ships and satellites, networked
with ground receivers and search-and-rescue centers. A ship, plane or
person can activate an emergency distress beacon, which transmits a
signal that satellites can detect. The satellites report the distress
call’s location to rescuers nearby, who can use it to narrow down
their search area.

The wearable antenna would transmit a distress signal if the user
activates it. It transmits a low-frequency signal, which is an impressive
feat for such a small antenna. In field trials, a person wearing the
life vest who was marooned at sea could be pinpointed within a few minutes,
the ESA says.
