An idea is born: Brenda McCaffrey, an electrical engineer, started running with a heart rate monitor after her mother's Alzheimer's disease diagnosis left her worried about protecting her own brain health. "To protect your mind you need to have good blood flow to the brain, and your heart needs to be at a certain heart rate to do that," she explains. But while she loved her fitness gadget, she wasn’t enamored with how it looked. So she took matters in her own hands and designed the Via Heartbeat bracelet, a chic piece of jewelry that works with any heart rate chest strap and glows when you hit your target heart rate zone.
Why it’s great: Unlike other heart rate monitor watches, there’s no programming required. "It needs no attention, so you can stay focused on the road," she says.
What’s next: McCaffrey’s tweaking the design to make it even sleeker and prettier. Eventually she wants the bracelet to monitor other biometrics related to mental health.
