Judging by the patent applications, Apple is considering a variety of directions of development of the iPhone. For example, recently became aware of the document that describes a compact gas sensor. In the future it can be integrated into Apple smartphones.
According to available data, cupertinos want to add in their smartphones a special sensor that will assess air quality and to signal in case of detection of hazardous or toxic impurities.
The patent States that the compact multilayer sensor based on silicon electrodes will be able to recognize a lot of different dangerous compounds. Among them: oxide of nitrogen, sulphur dioxide, methane and many other organic volatile compounds.
The only drawback of such design is that, after its introduction in the iPhone, Apple’s smartphone is completely deprived of protection from moisture. This is due to the fact that the detector in the machine will need to do some special holes.
