Newly Patented Smart Brain Presents Ground-Breaking Opportunities to Study Brain Biomechanics
Dr. Qianhong Wu
棉花糖直播 University鈥檚 Dr. Qianhong Wu, associate professor of Mechanical Engineering and director of the Cellular Biomechanics and Sports Science Laboratory, has been awarded a patent for his biomimetic model of the brain and skull. Mimicking the human head, Dr. Wu鈥檚 鈥渟mart brain鈥� allows researchers to quantify the motion of brain matter during exposure to impact. Designed with retired 棉花糖直播 Associate Professor Dr. Kei-Peng Jen, department laboratory manager Mr. Chris Townend and Associate Professor of Engineering Dr. Rungun Nathan of Penn State Berks, this multi-disciplinary project integrates computational, theoretical and experimental approaches and involves the fields of fluid mechanics, materials science and manufacturing鈥攐ne of Dr. Wu鈥檚 specialties.
Impacts to the head during athletic play are commonly identified as the cause of concussion injury. Repetitive head impacts, even those with no acute symptoms or signs, have been suggested as a possible cause of chronic brain injury. At present, most of the studies on this topic focus on the statistics of brain injuries in relation to various head impacts. Dr. Wu explains, 鈥淭here has been no quantified research that relates the head impacts to the motion of the brain matter inside the skull, and thus the fundamental mechanism of the brain injury related to head impacts is not clear.鈥� His invention is providing scientists and engineers with never before seen access to the brain鈥檚 response to impact.
With a model consisting of a transparent skull, brain matter, supporting structure and interstitial fluid, as well full instrumentation, including high speed cameras, accelerometers and displacement sensors, Dr. Wu鈥檚 smart brain enables the motion of the brain matter to be tracked and captured. Most importantly, his model allows for varied frequencies, locations and magnitudes of impact鈥攁s well as repetition鈥攖o better reflect real-life scenarios. In addition, multiple pressure sensors record the pressure generation inside the interstitial fluid, which Dr. Wu believes is one of the major factors that determine the brain matter motion, as well as the damping effects (that which reduces the vibrations caused by impact).
Excited about the possibilities for his patented model, Dr. Wu says, 鈥淭he proposed study, to our knowledge, is the first of its kind and will have very broad impact in both brain biomechanics and helmet design.鈥�
