Wearable Technologies Design Nighty Night Wristband by Meizhu Li Nighty Night is a wearable wristband designed to improve sleep quality. Nighty Night combines traditional Chinese acupressure with modern technology, using a low-frequency pulse current to stimulate acupoints on the wrist. The current passes between two electrode pads and creates even stimulation across the area between them, so the exact acupoint does not need to be located. The user puts on the band before sleeping and sets the intensity and the duration. The band is stored in a box that charges the device, and the electronic part can be removed for cleaning.
