Dr. Yong Shi of Stevens Institute of Technology was recently awarded a NSF subsidisation for his project coroneted "MEMS Umbrella-Shaped Actuator with Active Structure for Medical Applications." The grant was approved on scientific/technical virtue for trey years and will number approximately $300,000. The objective of the research is to design, cook up and test an umbrella-shaped micro-actuator based on an integrated micro/nanofabrication technique for thrombus retrieval in stroke therapy.
The proposed actuator consists of active structures that are precisely controlled by novel piezoelectric nanofibers. The functional precept of the proposed actuator is singular in that it hindquarters provide a dynamic shear force on blood clots in vascular arteries. This shear military unit can be fine-tuned to facilitate the separation of the blood clot from the wall of the vascular artery due to the shearing-thinning phenomenon, so enabling finish retrieval while minimizing the risk of damage to the arteries.This research will contribute newfangled fundamental knowledge in the areas of piezoelectric answer of nanomaterials as well as the mechanical behaviour of blood clots.
Dr. Shi, the Principal Investigator, has been an assistant prof in the Mechanical Engineering Department at Stevens Institute of Technology since 2004. He obtained his M.S and Ph.D in 2001 and 2004 respectively from Massachusetts Institute of Technology. His research interests admit functional nanofibers and nanocomposites, micro/nano actuators and sensors, RF, Bio, medical MEMS/NEMS systems design, modeling and fabrication . He won the ASNT society from the American Society of Nondestructive Testing in 2007 for the development of a nano acoustic sensor. Shi is likewise a member of several scientific and professional societies, including IEEE, MRS, ASME, and Sigma Xi.
Co-PIs working with Professor Shi on the picture are Professor Sundeep Mangla (M. D., Director of Interventional Neuroradiology , Associate Professor of Radiology, Neurosurgery, and Neurology ) and Professor Ming Zhang (M.D, Assistant Professor, Dept of Anesthesiology), both from SUNY Downstate Medical Center at Brooklyn, New York.

About Stevens Institute of Technology
Founded in 1870, Stevens Institute of Technology is one of the ahead technological universities in the world dedicated to learning and research. Through its broad-based curricula, nurturing of creative ingeniousness, and cross disciplinary research, the Institute is at the head of global challenges in engineering, science, and technology management. Partnerships and quislingism between, and among, stage business, industry, governing and other universities lead to the enriched surroundings of the Institute. A new mannikin for engineering commercialization in academe, known as Technogenesis�, involves external partners in launching business enterprises to create wide opportunities and shared value.
Stevens offers baccalaureates, master's and doctoral degrees in technology, science, reckoner science and management, in addition to a bachelor's degree degree in the humanistic discipline and loose arts, and in occupation and engineering. The university has a total registration of 2,040 undergraduate and 3,085 fine-tune students, and a worldwide online registration of 2,250, with about 250 full-time faculty. Stevens' graduate programs hold attracted international participation from China, India, Southeast Asia, Europe and Latin America.
