Taipei, May 8 (CNA) A research team led by Wen-Chau Liu, Distinguished Professor of Institute of Microelectronics and Director of High Speed Devices Lab at National Cheng Kung University (NCKU), southern Taiwan, has taken home with one gold and one silver medal at 40th International Exhibition of Inventions of Geneva for its “Nickel Oxide (NiO) Based pH-Sensor” and “Field-Effect Transistors (FETs) with Sensitization, Activation, and Electroless Plating Techniques” respectively.
The gold-winner, “Nickel Oxide (NiO) Based pH-Sensor”, is rather light in weight with 48.2 g and small in size featured in high sensitivity (59mv/pH@25oC), high linearity (0.999), good reproducibility, low cost, easy operation, and low energy-consuming.
According to Prof. Liu, the design of Nickel Oxide (NiO) Based pH-Sensor is unprecedented and after applying for patent it will enter mass manufacturing in the coming future.
Liu noted that in the past few years the pH biosensor has been widely used in various fields such as medical and health care, chemical industry, food industry, agriculture, fisheries ,and environmental monitoring.
The prototype of Nickel Oxide (NiO) Based pH-Sensor looks like a test strip and is likely to be developed into a handheld, disposable sensor, greatly enhancing its value in clinical application.
The silver-winning “Field-Effect Transistors (FETs) with Sensitization, Activation, and Electroless Plating Techniques” is an original device in which low equipment needs and costs, easy to operate, little energy consumption and environmental pollution, and short deposition time are highlighted.
Besides, the manufacturing process of the product has achieved the benefits of energy saving and carbon reduction, according to the team.
With 789 exhibitors from 46 countries and 1000 inventors around the world, 40th International Exhibition of Inventions of Geneva as one of top three world-renowned invention exhibitions has offered exhibitors opportunities to contact with promising inventors and companies during the exhibition.
