Discrimination of Red Wines with a Gas-Sensor Array Based on a Surface-Acoustic-Wave Technique.

We applied a thermal-desorption gas-chromatograph mass-spectrometer (TD-GC-MS) system to identify the marker volatile organic compounds (VOCs) in the aroma of red wine. After obtaining the marker VOC, we utilized surface acoustic waves (SAWs) to develop a highly sensitive sensing system as 'electronic nose' to detect these marker VOC. The SAW chips were fabricated on a LiNbO substrate with a lithographic process.

Cell migration of preosteoblast cells on a clinical gelatin sponge for 3D bone tissue engineering.

Using three-dimensional (3D) bone engineering to fabricate bone segments is a better choice for repairing bone defects than using autologous bone. However, biomaterials for bone engineering are burdened with some clinical safety concerns. In this study, we layered commonly found clinical materials, hemostatic gelatin sponges, in a novel manner to create a 3D scaffold for bone engineering purposes.

Detection of Particulate Matter of Size 2.5 μm with a Surface-Acoustic-Wave Sensor Combined with a Cyclone Separator.

A device to monitor particulate matter of size 2.5 μm (PM2.5) that has been designed and developed includes a surface-acoustic-wave sensor operating in a shear horizontal mode (SH-SAW) combined with a cyclone separator.

Cancer immunotherapy μ-environment LabChip: taking advantage of optoelectronic tweezers.

A cancer immunotherapy μ-environment LabChip, equipped with titanium oxide phthalocyanine (TiOPc)-based optoelectronic tweezers (OET) to achieve direct cell-cell contact, can be used to study the interaction between immune cells and other cells for real-time analysis of NK cells' behavior. In microfluidic devices, it is difficult to solve dead zone problems and observe dynamic cell-cell interactions. We have created a stable and static culture μ-environment which can enhance NK cell activities.

A novel dynamic sensing of wearable digital textile sensor with body motion analysis.

This work proposes an innovative textile sensor system to monitor dynamic body movement and human posture by attaching wearable digital sensors to analyze body motion. The proposed system can display and analyze signals when individuals are walking, running, veering around, walking up and down stairs, as well as falling down with a wearable monitoring system, which reacts to the coordination between the body and feet. Several digital sensor designs are embedded in clothing and wear apparel.
