This course helps electrical and computer 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. Students put together what they have learned in prior courses and experiences, 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.

Throughout this rigorous semester-long course, students work in self-chosen teams of 2 or 3 to envision, design, implement, and document a project of their own choosing. Teams are provided support from the dedicated course staff, consisting of ECE faculty and teaching assistants, as well as other ECE departmental resources, such as the electronics and machine shop. Almost any project idea can be undertaken in this course, as long as it is safe, ethical, and has a level of design complexity commensurate with the rigor of the ECE Illinois curriculum. As such, students have incredible freedom to undertake any project of their choosing - perhaps some idea that has been lingering in their minds for the past three years. Although daunting, this freedom creates an environment that numerous students have called their favorite class.

How to Receive Credit for Senior Design

ECE 445 is one of several ways to satisfy the senior design requirement for bachelor degrees in EE or CE. Other methods for satisfying this requirement exist. If you utilize one of these other methods, you may be required to complete the special circuit to satisfy the hardware design requirement of the EE curriculum.

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.
