The natural building of the human arm is optimal in all aspects of structure, weight, control, actuation, sensing, and self-healing. Hence, designing a prosthetic arm that replaces a lost arm is considered a very challenging task. Engineers and designers have strived throughout the years to design lightweight affordable reliable and user-friendly prosthetic arms with the maximum possible degrees of freedom and grip strength to satisfy users’ expectations. However, a large percentage of amputees end up rejecting the prostheses available to them due to difficulty in control, heavy weight, maintenance complications, among other problems. Many other amputees across the world cannot afford, or do not have access to, advanced prosthetic arms. Emerging technologies, such as 3D printing and smart materials, can enable more successful prostheses to be developed. In this presentation, innovative designs of prosthetic arms that were developed in the last four years at CSUN will be presented. This includes (1) MataPro-1: a biomimetic prosthetic arm actuated using shape memory alloy (SMA) wire actuators, (2) MataPro-2: a lightweight prosthetic arm with an innovative locking and SMA stroke-amplification system, and (3) Hercules-1: a reliable prosthetic arm with wrist rotation and tactile feedback system.
About the Speaker:
Dr. Peter Bishay received his PhD in Mechanical and Aerospace Engineering from University of California, Irvine (UCI) in 2014. He joined California State University, Northridge (CSUN) in Fall 2015 and established the “Computational Mechanics and Smart Structures” Laboratory. He published more than 30 research papers at reputable journals and conference proceedings covering different computational mechanics, composite and smart structures, aerospace structures and engineering education topics. He founded two new research-based senior design projects at CSUN, namely “Smart Morphing Wing” and “Smart Prosthetics.” He taught various undergraduate and graduate courses as an instructor in four different Universities in New Jersey, Washington, and California. He supervised nine Master students in the last five years. He served as a technical reviewer for over twenty journals in the last five years. Dr. Bishay is the recipient of the “Outstanding Engineering Achievement Merit Award” (2017) and the “Future Technology Leader Award” (2018) from The Engineer’s Council. In 2020, he received an early promotion to the rank of Associate Professor at CSUN.
