This course helps electrical engineering seniors make the transition into industry through self-chosen team projects. To do so, the course emulates the day-to-day life of a real engineering design environment creating what numerous students have called their favorite class. Students put together what they have learned, develop teamwork and leadership skills, and gain in-depth practical knowledge in a topic that excites them. Moreover, Senior Design Projects make a good addition to a resume. Many employers consider a good Senior Design Project to be just as valuable as internship experience.

Ingenuity Article: Both teams had high praise for the ECE 445 experience. "I felt that the class was a type of final exam for my education," said Willenborg. "It proves that I can do engineering. It's a hands-on test to see what you've learned here." Sengupta had a similar view: "The greatest thing about 445 is that it's all you. At the same time, the worst thing about 445 is that it's all you. This class relies on your ability to have self-discipline, motivation, and endurance."

Low Cost Myoelectric Prosthetic Hand

Low Cost Myoelectric Prosthetic Hand

Featured Project

According to the WHO, 80% of amputees are in developing nations, and less than 3% of that 80% have access to rehabilitative care. In a study by Heidi Witteveen, “the lack of sensory feedback was indicated as one of the major factors of prosthesis abandonment.” A low cost myoelectric prosthetic hand interfaced with a sensory substitution system returns functionality, increases the availability to amputees, and provides users with sensory feedback.

We will work with Aadeel Akhtar to develop a new iteration of his open source, low cost, myoelectric prosthetic hand. The current revision uses eight EMG channels, with sensors placed on the residual limb. A microcontroller communicates with an ADC, runs a classifier to determine the user’s type of grip, and controls motors in the hand achieving desired grips at predetermined velocities.

As requested by Aadeel, the socket and hand will operate independently using separate microcontrollers and interface with each other, providing modularity and customizability. The microcontroller in the socket will interface with the ADC and run the grip classifier, which will be expanded so finger velocities correspond to the amplitude of the user’s muscle activity. The hand microcontroller controls the motors and receives grip and velocity commands. Contact reflexes will be added via pressure sensors in fingertips, adjusting grip strength and velocity. The hand microcontroller will interface with existing sensory substitution systems using the pressure sensors. A PCB with a custom motor controller will fit inside the palm of the hand, and interface with the hand microcontroller.
