If you’ve ever found yourself nodding off while driving, you know how terrifying that can be. Thousands of people are killed or injured each year from tired driving, and these wearable vibrating ear clips by Fujitsu could be the solution. A sensor detects when the wearer is nodding off by watching heart rate and blood flow, and sends a vibration to a plastic necklace that wakes the wearer up. The possibilities for this technology are endless, spanning from lowering insurance rates to keeping long-haul truck drivers safe at the wheel. That's why getting proper sleep is important.
