Research Brief

Flexible OLED: Roll Up Your Mobile devices and carry them in your pocket

Portable devices seen in movies, such as paper-thin flexible mobile phones and rolls of plastic film which can be transformed into televisions, may not exist only in the realm of sceience fiction in the future. Associate Professor Mei-ying Chang and Professor Wen-yao Huang of the Department of Photonics invented three materials that are critical in developing flexible organic light-emitting diode components. The three meterials comprise flexible universal planes for display and electronic applications; flexible, transparent, conducting thin films; and deep-blue polymer light-emitting meterials. This development may enhance the portability of photoelectric devices such as televisions and mobile phones.

Portable Radars Guarantee Dairy Quality

Professor Tzyy-Sheng Hong of the Department of Electrical Engineering spent 6 years developing portable raders, garnering the interest of an American dairy system developer. The two parties signed a licensing contract worth US$2 million and an additional 3% royalty from annual global sales, which became the largest technology transfer in the history of the Taiwanese information and communications industry. This innovation can remotely and precisely detect the physiological conditions of animals and detect the presence of abnormalities. Because the portable raders detect the heartbeat, pulse, and breath, the physiological conditions of animals can be consistently monitored, enabling effective control of the quality of animal products by preventing infected meat and dairy from entering into the market. 

Urine Testing Toilets: Collaborating with the Sanitarywaew Industry for Smart Toilets

Professor Che-Hsin Lin of the Department of Mechanical and Electro-Mechanical Engineering spent five years with his team developing a novel liquid sensor. It takes merely one second for the sensor to gather data on the acidity, temperature, and ion concentration of urine, saliva, or sweat. The data, once available, is uploaded to the cloud, allowing users to monitor their or their family's physical conditions though a smartphone. This liquid testing technology developed by Professor Lin and his team can be applied to numerous areas, including elderly longterm care, quick medical screening, oral health, smart clothing that features physiological data collection, and water quality monitoring. According to Professor Lin and his team, '"the testing is both fast and effective, and the results can be immediately displayed on a smartphone." Professor Lin noted that by integrating the technology into smart-water meters, people will be able to monitor home water quality by phone, thereby securing drinking water safety. In addition, the technology is excellent for agricultural, aquacultural, and river environmental monitoring. As for saliva testing, it is useful for preventing tooth decay and periodontal disease and for other oral care purposes. 

5G Mobile Phone with Eight Antennas

Professor Kin-lu Wong of the Department of Electrical Engineering researched the applicationa of multiple-input and multiple-output (MIMO) technology in mobile phones and developed the only practical design to date featuring eight antennas. Wong explained that  because the main function of a mobile phone antenna is to receive signals, the eight-antenna design opens eight gates for signal transmission. For example, a mobile phone with single antenna requires 4 minutes to downlord a 500MB movie, whereas a mobile phone with eight antennas only requires 30 seconds for the same task under the same bandwidth. Testing results revealed that under 8 x 4 MIMO, eight-antenna devices reached a mobile traffic rate of 24.6 bps/Hz, four times faster than conventional single antenna devices did. Eight-antenna devices are expected to operate eight times faster than single antenna devices under 8 x 8 MIMO.
