(Daejeon=Yonhap News) Jae-rim Lee = A Korean research team created a three-dimensional touch technology that can sense location and pressure information simultaneously.

 

On July 2^nd, the National Research Foundation of Korea (NRF) announced that Seoul National University Prof. Seung Hwan Ko’s research team published their research in Nature Communications on June 13^th.

 

3D touch is a technology that can perform different tasks by sensing the force of the touching finger.

 

Apple Inc. used 3D touch in their iPhones, gaining public attention.

 

Their system combines a touch panel and a force sensor, which indirectly measures the approximate magnitude of the pressure being applied.

 

On the other hand, Prof. Ko’s team designed a method in which a single sensor can detect two types of information, rather than using two separate sensors for force and location. This method resulted in higher accuracy.

 

The new 3D touch sensor uses silver nano material.

 

It is possible to use sensors on curved displays or even human skin, since the fabrication can be done on transparent, flexible substrates.

 

The team created micro-sized wavelike patterns on the electrodes with laser. They were able to simultaneously measure location and pressure.

It was explained that the sensor can detect pressure according to the unique surface pattern of the electrodes when a finger presses it.

 

Attaching the system to the forearm of an actual person and using a simple Bluetooth module, the user could successfully draw a treble clef or a star.

 

Prof. Ko commented that “we created a micro-sized wavelike structure which, with the current method, is unable to crate. This kind of transparent, flexible 3D touch can be used as an innovative input device for wearable devices.”

 

However, the team added that there is much room for optimization for the technology to be commercialized.

 

The research was funded by the Ministry of Science and ICT · NRF Basic Research Project.
