A new alarm clock by Axbo measures sleep patterns and wake a user up within a specified time window (e.g., 15 minutes, 1 hour) that's harmonious with the natural sleep cycle. For example, a regular alarm clock set for 7:00 AM might wake a person up during a deep sleep period, causing grogginess and low energy throughout the day, while this clock would know to sound its alarm in accordance with the natural sleep cycle's progression to a waking state. A wireless wristband monitors sleep cycles and transmits these signals to the clock. Axbo's alarm clock costs $245 USD and is available for delivery as of today.
