Apple’s already removed the headphone jack in the iPhone 7, but are other features coming next?
On Tuesday, the U.S. Patent and Trademark Office (USPTO) awarded Apple with a patent for a technology that would help the company remove an iPhone’s home button and bake the feature—as well as its Touch ID fingerprint sensor—directly into its smartphone’s glass.
The innovation uses an electrostatic lens that connects the connect the screen and sensors, allowing the device to accurately read fingerprints on the screen.
Depending on the position of these lenses, relative voltage and shape, the layer or layers are able to shape or bend the electric field associate with the user’s finger, reports AppleInsider.
These specially designed lenses would also reduce the spreading of the electric field of a user’s finger when placed on the screen, as this type of bending can sometimes offset a fingerprint’s natural dispersion.
