NeoMare has developed an armband, called LifeSaver, equipped with an emergency flotation mechanism. The device contains a small chemical cartridge that, when activated, rapidly inflates a balloon with a volume of approximately 8 liters. In an emergency, pressing a button triggers the inflation, creating a buoyant aid designed to help a person stay afloat until assistance arrives. The inflation process uses a proprietary chemical reaction involving a light gas, such as hydrogen, contained in a stable and controlled form. This reaction allows a small quantity of material to expand into a larger flotation device when needed.
