INTRODUCTION
Technology available today is enabling what yesterday was a dream Trends in consumer electronics such as miniaturization, low power operation, and wireless technologies have spurred the invention of miniature devices that hold the potential to revolutionize lifestyle
THE NEED
Train students on design and development of wireless miniature medical devices that can revolutionize healthcare
A SYSTEMATIC APPROACH TO DESIGN OF PILL-SIZE MEDICAL DEVICES

ME-392-03 SPECIAL TOPIC: MINIATURIZED WIRELESS MECHATRONIC SYSTEMS
GOAL OF THE COURSE: To provide students with advanced knowledge to design a self-contained wireless mechatronic device focusing on medical applications INTENDED AUDIENCE AND PREREQUISITES: Graduate students in ME, EE, CS or BME interested in the design of mechatronic devices with emphasis on miniaturization and wireless transmission of data and power. Students should have basic knowledge of programming, electrical circuits, and mechatronics TOPICS COVERED: Programming of wireless microcontrollers and data acquisition and transmission from sensors and to actuators STRUCTURE OF THE COURSE: PHASE 1 (approximately 15 class hours) • Overview of medical pill-size devices, identification of crosscutting constraints and definition of a general system architecture • Overview of wireless microcontrollers for miniaturized low-power applications and wireless powering • Basis for selection of the hardware used in the course (Texas Instruments CC2530 and bqTESLA100LP) • Basics of programming the CC2530 in a C environment (IAR Embedded Workbench) – I/O Ports, Interrupts, Timers, Serial Ports, ADC, Interface with a PC, Wireless communication PHASE 2 (approximately 7 class hours) • Miniature sensors – accelerometers, magnetometers, temperature sensors, humidity transducers, chemical sensors, photodetectors, encoders, etc. • Miniature actuators – brushless and brushed DC motors, electromagnets, linear actuators, etc. • Connecting sensors and actuators to the wireless microcontroller PHASE 3 (approximately 20 class hours) • Project work – Each group of students selects an application (mobile robots, environmental monitoring, medical applications, underwater exploration, etc), identifies the system specifications and designs a wireless robot to fulfill the application requirements. HARDWARE LAB RESOURCES: each group has a PC with proper software installed (MatLab/Simulink, IAR Embedded Workbench, ProEngineering/Creo, Eagle, National Instruments Labview), a development kit for the wireless microcontroller, a development kit for wireless power transmission, oscilloscopes, power generators, multimeters, and signal generators. Rapid prototyping is available for developing the external shell of the designed device. PCB prototyping is also available for each group. Technical and scientific publications are available to properly derive application related specifications. STUDENT GRADING: Students’ final grades are based on four homework assignments and a final project report COURSE ASSESSMENT: Auto-assessment questionnaires covering the topics of the course are provided to students at the beginning and at the end of the course. Additionally, each student provides an anonymous feedback on the course and the instructor through the Vanderbilt Online Instructor and Course Evaluations system
Outcomes of the First Offering
NUMBER OF STUDENTS ENROLLED: In Spring 2012, we were able to offer just six seats because of limited class space available and the specialized instrumentation required. Also, since this course was being taught for the first time, we wanted to see the outcomes before increasing the number of seats STUDENTS’ FEEDBACK: Average score for both the course and the instructor was 4.5 out of 5. One of the comments was: “One of the best courses I have taken in my life! Thanks for giving us this opportunity to take a course like that in Vanderbilt” The PROFILE OF THE STUDENT WHO SEEM TO LEARN MOST from this class has a solid mechatronic background. Unless an operative system is used on board the microcontroller, a strong background in programming does not seem to be a strict requirement
