# Necklace Shakes You Awake Detects When You Doze Off By DANIEL MENDOZA | Published 2007-09-30 | Unique Source: Trend Hunter, https://www.trendhunter.com/trends/wearable-nap-alarm References: [techeblog](http://www.techeblog.com/index.php/tech-gadget/top-10-strangest-japanese-gadgets-and-accessories) Takanoha's "Nap Alarm" is a [wearable, low-cost gadget](https://www.trendhunter.com/trends/retimer) to keep you awake. The Japanese invention is placed behind the year, and vibrates should you fall asleep. The little gizmo detects the speed at which your head falls to determine if you are actually dozing off. Pretty nifty, but I still recommend stopping for a rest instead of risking falling asleep behind the wheel. The Nap Alarm sells for 1,450 Japanese yen, or about $12. ## Trend Insights (Trend Hunter) - Score: 3.3/10 - Popularity: 47% | Activity: 43% | Freshness: 8% - Audience gender: 10% men, 90% women - Primary generations: Millennial - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Unique](https://www.trendhunter.com/unique) > [Bizarre](https://www.trendhunter.com/bizarre) ## Key Themes ### What's Driving This Trend - **Wearable Alarm Technologies:** Innovative alarm technologies that can be worn and prevent accidents while driving. - **Safety Wearables:** Wearable technologies that are designed for safety measures. - **Low-cost Wearable Devices:** Affordable wearable devices that redefine the tech industry. ### Who This Affects Most - **Automotive Industry:** Developing innovative tech to prevent accidents caused by sleep deprivation and fatigue while driving. - **Healthcare Industry:** Designing wearable devices that monitor and prevent sleep-related health issues. - **Consumer Electronics Industry:** Manufacturing affordable and innovative wearable technology that can be applied in different domains. ## Related on Trend Hunter - [AI-Powered Nap Timers](https://www.trendhunter.com/trends/napping-device.md) - [Nap-Inducing Lulling Robes](https://www.trendhunter.com/trends/zzzn-sleep-apparel-system.md) - [Slumber-Inducing Wearables](https://www.trendhunter.com/trends/sleep-devices.md) - [Nap-Detecting Smartwatches](https://www.trendhunter.com/trends/fitness-smartwatches.md) - [Silent Wake-Up Wristbands](https://www.trendhunter.com/trends/wakeband.md) - [Silent Wearable Alarm Clocks](https://www.trendhunter.com/trends/silentwakeup.md) - [Contactless Smart Sleep Devices](https://www.trendhunter.com/trends/remwave-sleep.md) - [Sleep Disorder-Detecting Pajamas](https://www.trendhunter.com/trends/smart-pajama-top.md) - [Posture-Aligned Travel Pillows](https://www.trendhunter.com/trends/sleeper-hold-travel-pillow.md)
