Altitude sickness is one of the most common health problems for travellers. When we are put in a low pressure and hypoxia-inducing environment, our body will suffer from some ill reactions. It has been proven that breathing in oxygen may release us from altitude illness to some extent. For this problem, the OXYGENE comes in as quite new concept in the form of an oxygen-generating bottle. The drinking water is electrolysed into oxygen and hydrogen and provides oxygen for consumption. The hydrogen is stored and reacts with a little amount of oxygen in the air to generate electricity in the fuel cell slowly. The generated electricity is recharged into the lithium polymer battery to extend its lifespan. The intelligent system may detect bodily conditions by multiple sensors and modifies the oxygen supply, thus eliminating over-dependency on oxygen.
