A new patent published by the US Patent And Trademark Office, suggests Force Touch could have an expanded role in the future on the Mac, with the development of a new pressure-sensitive Touch Bar, reports MacRumors.

The patent offers visual examples of how force-sensing technology would be implemented in a MacBook Touch Bar, with Force Touch circuitry surrounding the touch-sensitive OLED strip.

"The secondary display and force-sensing circuitry may be encapsulated between two glass layers that are bonded to one another by a frit. In some embodiments, the force-sensing circuitry is formed from or constitutes part of, the frit," reads the abstract  of the patent application Force Touch sensors were introduced for the first time with the first-generation Apple Watch and they allow the screen to identify the touch pressure in order to perform different actions based on touch intensity.

This technology was then introduced to the MacBook trackpad in 2015.

It was also made available on iPhones and it was known as 3D Touch. Later with iPhone XR, Apple decided to replace 3D Touch with Haptic Touch for a better experience.
