This crazy technology will make mobile phones without buttons possible

Sentons ultrasonic sensor technology can turn any surface of your smartphone into a button capable of performing any action, without the need for design compromises or external physical elements

Yesterday we lived the day of the beasts on the Android platform, with the arrival of the new ASUS ROG Phone 3 and Lenovo Legion Phone Dual for liven up the mobile market gaming incorporating in both cases ultra-powerful hardware and a curious functionality that anticipates us the future of physical buttons on our smartphones which, surprise, also have their days numbered!

It’s not crazy to think about it, mobiles have been simplifying design, connectors and components for years at least on the outside, to become clean glass and metal sandwiches where the most important thing plays in the shade, under the hood. This time BGR told us, echoing Sentons’ crazy technology that can turn any surface into a button, being able to perform any action by pressing on the frame of the devices or even on its back.

Sentons’ technology seemed like a Hollywood thing, but it is already a reality in the present

It seems that the journey of the physical buttons in this industry is about to end, because Sentons has already implemented its ultrasonic sensors in the frameworks of the new mobiles gaming from Lenovo and ASUS successfully, equipping them with pressure sensitive areas to use as triggers when playing.

Sentons makes us take another step in the search for the perfect smartphone, that 100% wireless mobile phone that does not have notches on the screen, buttons or connectors or ports that compromise its design

SDSwave by Sentons, this is the ultrasonic technology that comes direct from the future

We already had fast wireless charging technologies, also high-quality sounding Bluetooth headsets, and pretty much all smartphone accessories have been tending towards wireless design for years that avoids compromising the cleaner construction of the smartphone.

In any case, the buttons until now nobody could kill them because there was no technology Sentons SDSwave, which we had seen announced to hype in some tests Beta, but that seemed like a Hollywood movie until yesterday Lenovo and ASUS presented it to us in a commercial format and absolutely by surprise, providing them with advanced functionality to play and anticipating a valid way to remove any physical keypad of our devices already facing the future.

Namely, the SDSwave are ultrasonic sensors that use processors to detect touch on any surface, in this case on the phone frames and even on the back, using ultrasound waves that will translate into on-screen actions according to gestures or keystrokes.

ASUS ROG Phone 3 triggers allow gestures and extend the smartphone’s ‘gaming’ functionality

The technology seems to work very well for mobile gaming it allows us to configure button schematics with triggers on the frames, without the need for a physical button, and its use could be expanded in the future to change the volume, take a photo or activate basic actions on a smartphone such as answering calls, activating silent mode or turning off the terminal itself.

Sentons’ technology foundation is use ultrasonic waves similar to sonar arrays, placing piezoelectric transducers inside the touch surface so that they emit and detect changes on the mentioned waves, when we press or make a gesture on the surface. A pulsation would be equal to the change in wave vibrations ultrasound caused by the finger.

As if this were not enough, it also seems that the SDSwave are able to detect pressure, differentiating touches or long presses and different gestures, in addition to working on screens, aluminum or stainless steel to expand your possible use cases.

Sentons has provided the new ASUS ROG Phone 3 and Lenovo Legion Phone Dual with SDSwave sensors, but this hardware is now ready for mass marketing, so you could soon reach any other device that wants to extend the interaction functionalities or eliminate keypads that compromise its design. Almost magic, right?
