Apple Vice Presidents: Power Button with Touch ID in iPad Air 4 – “Engineering Breakthrough”

by Henry Brown

 

Apple VP of Product Marketing Bob Borchers and VP of Hardware Engineering John Ternus featured on the Same Brain podcast, discussing aspects of the current iPad lineup.

Fitting the Touch ID sensor to the iPad Air 4’s power button was “an incredible engineering feat,” Borchers said. Ternus explained that due to the narrow format of the button, it is difficult to achieve the proper accuracy of the sensor: the sensor must be very sensitive and request more detailed initial finger registration.

In the iPad Air model with a cellular module, engineers had to fit the antenna that occupies the top of the case and Touch ID. Since both instruments are highly sensitive, it was a separate task to isolate their operation from each other.

iPad Air 4 announced on September 15th. For the first time, it received the Apple A14 Bionic platform based on 5nm process technology, as well as a new generation Touch ID fingerprint scanner built into the power button.
