The ultimate goal of this research is to optimize the treatment options of vascular diseases and design better medical devices for these options. Vascular diseases and their effects, including carotid artery disease, stroke, and abdominal aortic aneurysms (see Two areas of VBBL research that have yielded funding and Figure 1), affect millions of Americans. In recent decades, press are the lab’s work on (1) understanding the blood flow the role of blood flow and its relationship with disease has and vessel structure relationship in native abdominal aortic created a common focus for both prevention and clinical aneurysms and (2) medical devices to complement carotid management of vascular diseases.

The ability to model biological flow for VBBL’s work on predicting the rupture potential systems experimentally and numerically is now an important of abdominal aortic aneurysms. The grant, entitled component to fundamental research of vascular disease. “Bioengineering Studies of Abdominal Aortic Aneurysm Fluid and Wall Dynamics,” will support a prospective clinical research study with the objective of investigating the central hypothesis that, once an aneurysm is diagnosed, the primary biomechanical determinant of rupture potential is the non-uniform arterial wall thickness, within the context of a dynamic assessment of aneurysm mechanics.

Close to 2 million people in the United States suffer from abdominal aortic aneurysms, defined as a 50% increase in the diameter of a segment of the aorta. The inability to fully assess the status of a patient’s abdominal aortic aneurysm has led to extensive research into other potential indicators of rupture or evaluative criteria for determining surgical repair.

Computer Engineering When normal motor function is impaired by amputation, trauma or disease, it is necessary to use techniques such as prosthetics and wheelchairs to interact with the environment. However, the controllability of a patient a low-power integrated wireless micro-system and (2) a portable neural signal decoder. The wireless sub-system records extremely low-level neural signals from several (e.g., 32) electrodes, amplifies, filters and digitizes these A key trade-off in this design is to minimize its power consumption so that (1) heat dissipation does not cause biological damage and (2) it can operate from relatively small amounts of power that can be inductively coupled in from an external source. can be substantially limited by his impairments: e.g., a patient with spinal cord injury may not be able to control a wheelchair by hand. In this case, it is extremely important to develop a brain computer interface (BCI) for which neural signals from the brain are sensed, amplified, filtered and decoded to control prosthetic limbs, electric wheelchairs, or other external devices, leading to a dramatically improved quality of life. BCI is defined as the science and technology of intelligent devices and systems responding to (1) neural processes in the brain that generate motor movement and (2) cognitive process (e.g., memory) that modify motor movement. Today, with advanced technologies in medical sensors, biocompatible materials, integrated circuit and computational neurosciences, such a BCI system becomes practically feasible. There is a strong interest from industry to commercialize and market a BCI system for both medical Figure 1.

Because this implant uses several discrete chips assembled on a printed circuit board, it is too large to be embedded in the skull as and non-medical applications. shown. Instead, it may have to be embedded in the larger There is currently a collaborative project being conducted clavicle. This would require long cables from the electrodes in BCI research between Carnegie Mellon’s Gary Fedder, Xin Li, and Jeyanandh Paramesh of the Electrical and Computer Engineering Department and Douglas Weber with the Department of Physical Medicine & Rehabilitation at the University of Pittsburgh School of Medicine. The major goal of our project is to develop a low-power wireless BCI micro-system. In particular, our project focuses on “minimally invasive” BCI technology using electrocorticography (ECoG) recorded from the cortical surface. ECoG has higher spatial resolution than EEG (electroencephalography) and is safer than single-neuron recording. The wireless interface proposed in this project has many advantages in terms of comfort and mobility. Most importantly, it reduces the risk of infection. cavity far away from the brain, for example, close to the to the implants and would raise concerns of infection. A second drawback with this system of Fig. 2a is that the circuits operate relatively inefficiently so that they require an on-implant battery. Ongoing work in our lab aims to find solutions to these problems. Their approach is to integrate all functions (amplification, filtering, digitization, compression and telemetry) on a tiny piece of silicon. This ultra-low power chip would be power using on-chip coils that couple inductively to a remote power source. Concurrently, several groups within CMU are collaborating on a largely biodegradable scaffold that will connect the electrodes to the implantable chip. Our group at CMU also collaborates with UPMC to develop robust, bio-compatible recording electrodes and test in-vivo these complex, engineered implants.

Fenves Award dr. lee weiss is the 2007– 2008 recipient of the steven j. fenves award Robotics Institute Research Professor and ICES faculty member Lee Weiss was recently named the 2007– 08 recipient of the Steven J. Fenves Award. The Fenves Award is awarded annually to a faculty member who makes a significant contribution to systems research in areas relevant to ICES. This award will be presented to Dr. Weiss at the Carnegie Institute of Technology (CIT) Faculty Awards Banquet this spring. Dr. Weiss received the Fenves Award for his significant contributions to system engineering research in shape deposition manufacturing, micromechanical Velcro, inkjet printing technologies for biomedical applications and Fig. 2a.

ICES Director Gary Fedder says, “Lee Weiss signal processor. embodies the very essence of the Steven J. Fenves Award The second sub-system (Fig. 2(b)) is a robust decoder that takes the recorded neural signal as input and accurately predicts the kinetic parameters (e.g., direction, velocity, etc.) of targeted movement. Instead of considering the neural signal decoding as a general signal processing problem, we particularly focus on the aspect of hardware implementation with high mobility. Namely, the algorithms used for neural signal decoding must be implemented in hardware with small dimension, light weight and low power. The long-term goal of this project is to develop advanced micro-system technologies and apply them to clinical applications. Through collaborations with several multidisciplinary groups with Carnegie Mellon, the University of Pittsburgh Medical Center (UPMC) and the Allegheny General Hospital, this project will eventually lead to intelligent devices and systems that aid disabled people and significantly improve the quality of their life. as reflected by his significant contributions to systems engineering research with an impact on the real world. His service of three-plus decades at Carnegie Mellon reflects his unparalleled quest for bringing people of different backgrounds together by trail blazing new areas.” Dr. Weiss has been a contributor to systems research since before the existence of ICES and the NSF EDRC (Engineering Design Research Center). “He has been the keeper of the spirit of ICES by reflecting its goals and by being an exemplar researcher for others to follow,” continues Dr. Fedder. The “Steven J. Fenves Award for Systems Research” is presented annually to individuals for their contributions to systems research in areas that are relevant to the College of Engineering and ICES. Individuals considered for this award have made significant contributions to systems research in areas relevant to ICES, by furthering the goal of interconnecting people, physical, and information; development and demonstration of an engineered system; enhancing education in systems through the development of courses, publishing textbooks, or a body of knowledge that is of pedagogical importance; and causing a paradigm shift in systems research. 4 5 iNews • Spring 2008 Newsletter New ICES Center ices introduces new interdisciplinary engineering center on multiscale modeling coordinate research and educational activity in multiscale materials modeling across the Carnegie Mellon Colleges of Engineering and Sciences.

The ICES table was manned during these days by ICES faculty, staff, and students who worked with visiting children on the activity “Build a Bone.” This problem-solving activity gives participants a list of materials and parameters they must follow as they attempt to create a bone that will hold the most weight when tested. This year, a new record was set for the strongest bone, which held 24 lbs, and it resulted in attracting the media attention of WQED’s Rick Sebak. Sebak, who creates documentaries about Pittsburgh history, was filming at the Science Center on Friday for a new documentary called “Invented, Engineered, and Pioneered in Pittsburgh.” His film crew captured on tape the testing of the strongest bone by its young creator and by ICES Associate Research Professor Phil Campbell, who was working at the ICES table. Professor Campbell created the Build a Bone activity for National Engineers Week and is the ICES faculty coordinator for National Engineers Week activities at the Science Center. The documentary will premiere on WQED on Thursday, April 10.
