If you've ever wanted to crumple up a keyboard and carry it in your pocket, researchers from the Sejong University in Korea have created a gadget that can do just that. Bendable portable keyboards have already been on the market for quite some time, but they are not very flexible and take up a significant amount of space.

New technology uses silicone rubber embedded with conductive carbon nanotubes.The researchers have created a keyboard that is so thin, tough and flexible it can be crumpled up and put in a pocket with no damage. sensor on a multilayered soft sheet. These devices are hard to make, and because of their stiff materials, can only withstand a little bit of bending or rolling.

To guide users where to press, the researchers drew squares on the surface of the sheet to represent keys for each letter, number or other character. The new keyboard uses an artificial neural network to teach it to identify the intended letter or character based on the location and pressure of pushes, as well as resistance, on the keyboard.

The researchers claim the keyboard works perfectly and 'outperformed all existing portable keyboards in terms of functionality, flexibility, disposability and cost'. In fact, they estimate that the keyboard would cost just one dollar, easily replaceable if it stops working. Ji Sik Kim and their colleagues wanted to develop a keyboard that could withstand the rigors of everyday life, including complete folding and harsh crumpling.

The study appeared in ACS Applied Materials & Interfaces.

Press Release - Feb. 17, 2022

경북대학교(총장 홍원화)는 스마트융복합재난관리교육연구단의(단장; 이기하 교수) 석사과정 신호근, Suman Timilsian 박사 및 김지식 교수 등이 구조물에서 획득된 미케노 발광기반의 디지털 영상 이미지를 이용하여 정량화된 균열 첨단 변위를 계측함으로써, 구조물 안전진단의 편의성 및 경제성을 획기적으로 개선시킬 수 있는 새로운 균열 탐지 및 평가 기법을 개발하였다고 16일 밝혔다.

해당 성과는 2월 14일 자연과학 및 공학 분야의 저명 학술지 ‘어드밴스드 사이언스 (Advanced Science, Impact Factor: 16.806, JCR: 5.24 %)’에 온라인 게재 되었으며, 연구팀이 개발한 새로운 재난관리 기법은 우주 항공 및 기계 건축 구조물 등의 복잡 거대구조물 안전진단 분야에 있어 게임 체인져 기술이 될 것으로 기대된다.
