Wireless sensor practicals

Summary

In this course, students will design, fabricate, and characterize a wireless sensor wearable. Students will design a custom-chosen wearable around a standardized wireless microcotroller platform, including the electronics and packaging, and will characterize and analyze its performance.

Content

Keywords

Design, Sensors, IoT, wireless, wearables, packaging

Learning Prerequisites

Required courses

Entire MT curriculum through BA5.

Important concepts to start the course

Basic electronics including microcontroller-based design

PCB design

CAD for 3D printing

Learning Outcomes

By the end of the course, the student must be able to:

• Design a wireless sensor system
• Assess / Evaluate the performance of the part
• Assemble the wireless sensor, including package and electronics
• Plan The teaming and scheduling of the entire development
• Organize the workflow as a team

Transversal skills

• Assess progress against the plan, and adapt the plan as appropriate.
• Plan and carry out activities in a way which makes optimal use of available time and other resources.
• Evaluate one's own performance in the team, receive and respond appropriately to feedback.
• Communicate effectively, being understood, including across different languages and cultures.
• Communicate effectively with professionals from other disciplines.
• Identify the different roles that are involved in well-functioning teams and assume different roles, including leadership roles.
• Demonstrate a capacity for creativity.
• Make an oral presentation.

Teaching methods

Teaching will occur through:

1. Introductory lecture
2. Periodic lectures and recorded videos / other online resources as needed
3. Regular progress meetings with the professor
4. TA support in labs as needed, as well as acccess to DLLs

Expected student activities

Students will perform the following activities:

1. Design of PCB and board-level electronics
2. Design of 3D printed packages
3. Fabrication of electronics
4. Assembly of the integrated sensor
5. Characterization of the integrated sensors
6. Summary preparation and report writing and presentation

Assessment methods

Assessment will be based on:

1. Written report (70%): Quality of report, details of analysis and design vs. design and analysis metrics, overall results of wearable design
2. Oral report (30%): Quality of presentation and handling of Q/A.

Supervision

Resources

Virtual desktop infrastructure (VDI)

Yes

Bibliography

Design guides for microcontroller interface will be provided, with links to manufacturer specifications.
