There’s an experimental necklace developed by the Georgia Institute of Technology that reminds you to take your medicine. Users must first ingest a special pill, along with your other pills, that contains a small magnet, which then activates the necklace. The necklace then records when, exactly, you swallowed the pills. That way, your nurse or caregiver can know when, or if, you’ve taken your medicine.

See? Not all tech is silly.
