OsteoApp

Researchers: Professor Shwetak Patel (PI) Josh Fromm, graduate student, electrical engineering Alex Mariakakis, graduate student, computer science and engineering About every three seconds, someone suffering from osteoporosis breaks a bone. Even so, most cases of osteoporosis still go undiagnosed, since the two current methods for detecting the disease are expensive and unwieldly. But what if people…


Smart Eyewear

Researchers: Professor Arka Majumdar (PI) Shane Colburn, graduate student, materials science and engineering Alan Zhan, graduate student, physics As people age, their eyesight almost always gets worse. According to the Vision Council of America, approximately 75 percent of adults use some sort of vision correction. But for a patient, buying new glasses every time their…


UW BIOFAB: a cloud laboratory for genetic engineering

Participants: Professor Eric Klavins (PI) Justin Vrana, graduate student, bioengineering Orlando DeLange, postdoctoral researcher, electrical engineering Michelle Parks, staff, electrical engineering Biomedical laboratories, entrepreneurs, and researchers need data to develop medical therapies. But the complex experiments the process requires can be error-prone, often leading to longer timelines and higher costs. Now, a team led by…


IRA, the robot surgical assistant

Researchers: Professor Blake Hannaford (PI) Dr. Laligam Sekhar, neurosurgeon, UW Medicine Niveditha Kalavakonda, graduate student, electrical engineering Major surgical procedures require a master surgeon and one or more assistants. On top of that, the current high cost of surgical care demands the best use of highly skilled assistants. But this makes it hard for new…


Haptic Passwords

Researchers:  Professor Howard Chizeck (PI) Junie Yan, Student, graduate student, electrical engineering Mobile/On line transaction fraud from credit cards is over $10B annually, and existing authentication methods are not secure, and are easy to compromise. The new, forgery-proof Haptic Passwords method verifies your identity and secures on-line and mobile transactions. By taking advantage of the tremendous computing power…


Active self-cleaning technology for solar panels

Researchers: Professor KarlBöhringer (PI) Di Sun, graduate student, electrical engineering By microfabrication process, University of Washington Electrical Engineering (UW EE) Professor Karl Böhringer and UW EE  graduate student Di Sun can create micro-sized patterns on a glass surface. By vibration, water droplets can be guided along the patterns and clean away surface contaminants. In a handout,…


Enabling district shared parking via energy harvesting wireless sensing technology

Participants: Professor Joshua Smith (PI) Alex Brennan, senior planner, Capitol Hill Housing Zerina Kapetanovic, graduate student, electrical engineering Saman Naderiparizi, graduate student, electrical engineering There is a growing body of evidence in the urban planning community that as a society, we are building many more parking spaces than are actually needed, because so many parking spaces are…


simsong.org

Researchers: Professor Les Atlas (PI) Ruobai Wang, graduate student in electrical engineering Simsong.org will allow users to discover new music through music they already love. Using a super-quick match approach called “context sensitive hashing,” along with the power of machine learning based signal processing, simsong.org is different from usual content-based music retrieval systems in that it…
