This paper describes a platform for real-time sensing of dissolved oxygen in a flowing microfluidic environment using an oxygen-sensitive luminescent dye (platinum octaethylporphyrin ketone) integrated into a micro-oxygenator device. Using a phase-based detection method, the luminescent decay lifetime of the dye was consistent with the linear Stern-Volmer relationship using both gaseous and aqu...

Film bulk acoustic resonators (FBARs) are widely applied in mass bio-sensing and pressure sensors, owing to their extreme sensitivity and integration ability, and ability to miniaturize circuits. A volatile organic compound (VOC) sensor with a polymer-coated diaphragm, using FBARs as a strain sensing element is proposed and optimized. This vapor sensor is based on organic vapor-induced changes ...

The use of wireless sensor networks (WSN) in health-care has been rapidly increased in the last few years. Miniaturization of sensor nodes, in-body data communication, bio-compatibility are the main outcomes of the on-going extensive research on nano-technology, wireless communication and bio-medical engineering, respectively. Sensing of various life-critical physiological signals such as heart...

This paper presents the construction of a six-legged bio-mimicking robot. The mechanical design includes the actuation design based on shape memory alloy (SMA) actuators and the locomotive mechanism. The motion control system implements various gaits for the robot to maneuver. The sensors used in the control system include the accelerometer, the compass sensor and the step sensors. We develop a...

The power of foodomics as a discipline that is now broadly used for quality assurance of food products and adulteration identification, as well as for determining the safety of food, is presented. Concerning sample preparation and application, maintenance of highly sophisticated instruments for both high-performance and high-throughput techniques, and analysis and data interpretation, special a...
