NCKU wins gold, silver at invention show in Geneva


TAIPEI–A research team led by Wen-Chau Liu, Professor of Institute of Microelectronics and Director of High Speed Devices Lab at National Cheng Kung University (NCKU) from 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.
