As we all
know, the new iPhone 6s was released a few weeks ago. With the many new
features of this phone, it couldn't have been done without the best of
engineers. From mechanical engineers to mechanical engineers, this new device
has exceeded the expectations of any Apple lover.
The newest and
most predominant feature of the new phone is the force touch feature which
allows users to interact with the phone in a 3D way. When you push on the
screen more forcefully, the phone brings up more options, almost as if you were
to "left click" on your iPhone. Well, how does it work? Engineers
have been working day and night to figure out how to do this and they are proud
to announce how it works. The screen is made up of multiple layers which have
tiny sensors in them called strain gauges. Hong Tan, professor of
electrical and computer engineering at Purdue University explains: “Strain gauges are basically those materials that when
you bend them, you change the electrical signal that comes out." With
these change in electrical signals, the software calculates how much force you
are applying using, what Apple calls "force centroid." The
technology of the 21st century is only improving; it makes me wonder what
the Engineers of tomorrow have in stock for the future.
