Since last year there was information that indicated that Apple intends to implement new sensors in iDevices with the help of which they would detect if a terminal has been hit, has been subjected to extreme temperatures or has been affected in any way by user. In a recent invention patent of the Apple company it was discovered that new sensors for detecting contact with water could be implemented, the sensors working with the help of a soluble "glue" that could isolate an opening between two components that could be affected by water.
In one potential solution, Apple describes an "immersion detection mechanism" included as part of the internal components of a device. This water sensor could be covered in a water-soluble conductive glue that would electrically insulate the gap between two conducting pieces. In the event that an iPhone or another device were to be submerged in water, this conductive glue would be permanently eroded by the water. The system would detect a change in impedance of the path, and would signal an alert to a data processor that would log water exposure events within the device.
The respective sensor would detect contact with water and when the device was taken back to the Apple store, the employees would very easily figure out what the problem was with it and would not receive it under warranty. On the other hand, Apple is thinking of connecting this type of sensor directly to the iDevice's processor and with the help of an application could read everything they record without the user being able to check in any way if the sensor has been triggered. No matter what Apple chooses, it is clear that an iPhone dropped in water cannot be received under warranty.
