Abstract

One of the most common reasons for replacing mo- bile phones is that the phone unintentionally is dropped in water or left outdoors. This problem has only been solved by the traditional way of using silicone gaskets and buttons to seal the phone. There are accessories in forms of waterproof bags or life- belts, too. The proposed solution integrates an active water- proof system in the phone itself in order to avoid water to leak into the phone destroying the hardware. The phone with silicone gaskets and buttons is addi- tionally equipped with a small cylinder with a mate- rial, that when it gets wet, produces an inactive gas that makes an excess air pressure in the phone. This cylinder is made in a way that after taking in water, a valve closes the cylinder and the gas flows into the phone (figure 1).
