According to Taiwanese site TechNews (Via Cult of Mac), the material composing the home button of the iPhone 5S will be made ​​of sapphire crystal, for unmatched strength.

The sapphire crystal would serve to integrate the biometric reader for fingerprint recognition.

This very strong mineral is already used on the iPhone 5 to protect the optics of the camera.

Furthermore, there will no longer be a physical key but a capacitive touch-sensitive button.

In addition, this material alters very little over time.

Latest rumors indicate that the production of the displays for the next iPhone is scheduled to start at Apple’s Asian supplier Sharp next month.
