There’s plenty of people-tracking GPS devices out there to choose from, but if you’re in need of something a bit more specialized, you may want to consider this latest device from Keruve, which is apparently intended specifically for Alzheimer’s patients. To that end, the system employs a GPS tracker bracelet that’s water-proof and can only be removed with a special tool — it can also apparently fall back on cell tower triangulation (otherwise known as A-GPS) provide a location when regular GPS is unavailable. As you can see above, that gets paired with a handheld unit that pinpoints the patient’s location on a map, but the entire kit doesn’t exactly come cheap, with it setting you back €850 (or about $1,340).
