Multiple poly-silicon nanowires (PS-NW\'s) coated with different high-k dielectric materials, HfO2, Al2O3, and TiO2, were fabricated and their pH sensing characteristics were compared. Sidewall spacer formation technique was used for the PS-NW\'s fabrication and all the high-k materials were deposited by atomic-layer-deposition (ALD). Following the high-k dielectric deposition, a 3-aminopropyltriethoxysilane (gamma-APTES) layer was coated as sensing membrane. It is found that the multiple PS-NW sensor coated with HfO2 exhibits the highest sensitivity and best reproducibility for pH sensing.

In the intensive care unit (ICU), the situations of the critical patients vary rapidly. To give the patient the necessary medical treatment, the medical staffs need to response in no time. However, making the diagnosis is not easy since there is tremendous information to be processed in ICU. In this paper, a prototype human-centric graphical user interface (GUI) based on ecological interface design (EID) is implemented by C# that is compatible with Microsoft Windows system. The human-centric GUI integrates the necessary information and will help the medical staffs to interpret them efficiently. The waveforms of artificial vital signs are displayed to show the variations of those signs instantly. Besides, the GUI can display the heart/lung/kidney indicators in radar charts to assist medical staffs aware of abnormal indicators in a visual way.
