Would You Use a Wearable Baby Monitor?

A new technology from Sproutling, a startup founded by former Apple and Google engineers, is a wearable baby monitor. By strapping the device around an infant's ankle, parents can determine their child's heart rate, movement, and mood. The environmental sensor also measures the humidity, noise levels, and...
