Research Brief

New Sludge Reduction Technology Original Electric Dehydration System Designed at NSYSU

Professor Yang Chin-Chung of the institute of Enviromental Engineering proposed a processing method different from the conventional pressure filtration approach and pioneered the use of electric power-assisted pressure filtration, naming it as an "electric dehydration system" for short. This novel system successfully combines two types of plate filter press (plate and frame filter press and recessed plate filter press) and can be applied to organic sludge dehydration. The novel electric dehydration system can significantly reduce the water content of organic sludge to 60%-65%, sludge cake volume by 30%-45%, and content of plasticizer and some pollutants in sludge cake. Therefore, this approach can lower the cost of sludge treatment by approximately half and alleviate the problem of landfill space, thereby constituting a sludge reuse and environmental protection. 

Customized Spinal Cord 3D Printing with Lastest Bone Materials

An additive manufacturing project was commissioned by the MOST to the following: Chair Professor Jacob Chih-ching Huang of the Department of Materials and Optoelectronic Science, Professor Che-Hsin Lin and Cheng-Tang Pan of the Department of Mechanical and Electro-Mechanical Engineering, Professor Jason Shian-Ching Jang of the Institute of Materials Science and Engineering of National Central University, Associate Professor Hsuan-Kai Lin of National Pingtung University of Science and technology, and Associate Professor Chung-Hwan Chen of the Department of Orthopaedics of Kaohsiung Municipal Ta-Tung Hospital, and his team at the Department of Orthopaedics, Kaohsiung Medical Univesity. After two years of work, they have successfully developed the first customizable replacement cancellous bone made of metallic glass through 3D printing. Patients will benefit from this locally desighed and manufactured product that not only substantially reduces the cost of lumbar surgery but also enhances the durabilitiy of the replacement bone.

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.
