The future iPhones, iPads, and Apple watches could have built-in sensors to detect noxious gases such as carbon monoxide, nitrogen dioxide, and nitrogen monoxide. Apple was granted a patent for sensors that can detect these gases that plague the environment. These toxic gases jeopardize our health and numerous smart air-purifiers have been launched so far to fend off the ill-effects. Lately, Tesla launched a specialized High-efficiency particulate air (HEPA) filter for its vehicles boosting a ‘Bioweapon Defense Mode’ for filtration mode.
Ingraining smartphones and watches with physical gas sensors seem like a spectacular innovation. However, to ingrain the physical gas sensor into an Apple device will require another chassis opening, a move that Apple has consciously been avoiding in order to maintain water-resistance in its devices.
The miniature gas sensing device encased in an external chassis opening will detect gases that comprise of volatile organic compounds such as ozone, nitrogen dioxide, nitrogen monoxide, sulfur dioxide, carbon monoxide and methane. It will also detect the presence of other toxic species including siloxanes, sulfates, phosphates and chlorides.
