Yanhui Bai, PhD candidate

His research area includes the modeling and simulation of MEMS actuators and sensors, applications of MEMS devices, as well as various types of MEMS fabrication techniques. Currently, he is designing novel MEMS micro-mirrors for optical coherence tomography (OCT) and confocal systems for biomedical applications such as endoscopes.

Mohsen Shahini, PhD candidate
mshahini
He is working toward an effective solution for the problem of manipulating micro-sized objects precisely and automatically. He proposes MEMS technology to fabricate the mechanical components of such manipulators which will enhance the dexterity and manoeuvrability of the system. That will also improve the throughput of multi degree of freedom micromanipulation tasks by fitting a number of micro/milli-scaled actuators into one workplace. Multiple of the manipulators can operate together in a conventional robotic-assembly-line fashion to implement more complex manipulation. To minimize the intervention of a human, the manipulation is automated by incorporating a visual-servo feedback mechanism into the controller. Artificial intelligence is efficiently employed to compensate for the poorly-known nonlinear effects of various micro forces, making the system robust against variation in parameters involved in the overall magnitude of the micro forces such as ambient and surface conditions.

Andrew S. Logan, PhD candidate

He is responsible for the development of MEMS based ultrasound transducers for catheter based imaging. A catheter based ultrasound imaging system will allow for improved diagnosis of vascular occulsions and better monitoring of a patient's treatment. Applying MEMS based technology will facilitate manufacturability and flexibility of the transducer system when compared to traditional technologies.

Yun Wang, PhD candidate
y83wang
Her research interest is focused on the design, modeling and fabrication of a capacitive humidity sensor based on capillary condensation. Micro/nano porous structures can highly enhance the condensation and adsorption of vapour due to capillary effect. Therefore a higher change of capacitance can be detected because of the higher dielectric of water. This device has high potential applications on biomedical systems or fuel cells.
