Nausea, that debilitating sense that something severely amiss in your stomach threatens rapid emission, can ruin an otherwise perfectly wonderful boat ride, airplane travel, or even a car trip. Nausea serves us by warning when we’re about to vomit when there’s a good reason such as spoiled food or eating or drinking too much. It’s helpful to have a biological warning before our stomach erupts. Nausea from motion sickness or other circumstance when there’s no biological imperative to rapidly void your stomach, however, ranks high on most people’s least favorite feeling list.
We wrote about ReliefBand Technology’s eponymous nausea relief wearable following its introduction at CES 2016. The original version delivers mild electrical pulses on the underside of the wrist to block nausea signals to the brain. Two years later, ReliefBand will be back at CES 2018 with ReliefBand 2.0, using what the company refers to as “a new level with state-of-the-art Neurowave technology.” The basic operational principle remains the same. The patented Neurowave Pulse Generator controls the electrical pulse. The original wearable’s fat teardrop face is gone; the pulse-emitting contact pieces on the inside of the wristband looks the same. The Reliefband 2.0 face has a dark LCD. The new version of the nausea sensation-blocking device looks like a typical fitness wristband so you no longer announce to those who recognize the device that you’re subject to nausea nor will people be as likely to ask why you’re wearing such an odd-looking watch.
According to a company news release, the new Reliefband generation enhances comfort, usability, and design. Reliefband applications include not only motion sickness, but also morning sickness, post-operative care, chemotherapy-induced nausea and vomiting (CINV), and virtual reality gaming.
