Design of Medical Instrumentation: BME100
It is with this background in mind that the course is taught a flexible and evolving way. It is built around the following basic topics:
- Linear systems: transfer functions and frequency response
- Electrodes for biopotential recording
- Basic electronics including operational amplifiers and the instrumentation amplifier
- Transducers for temperature, displacement, pressure, force, and flow
- Optical transducers and blood oxygenation measurement
- Computer interfaces and data acquisition
- Product development and regulation
Students have the opportunity to relate these topics to current engineering practice by
- Relating their learning to material in the scientific and professional literature
- Participating in a group project to discover the engineering involved in the development of an existing commercial product
When the course moved to online format in the last part of the Spring 2020 semester, the labs went online too and became demonstrations.
Modern Biomedical Engineering often involves designing interfaces between the body and the device, and the device and the outside world. Examples of the former include things as simple as a thermometer, or as complicated as a drug delivery device. Examples of the latter include computerized control of devices such as deep brain stimulators, and device readout such as displays of vital signs.
This course will introduce the student to the concept of graphical programming, so that engineers can design interfaces without the need for detailed line by line programming. This method allows you to use Labview and Matlab to design a block diagram that can be directly and automatically translated to appropriate computer code.
This idea not only allows the design of computer interfaces via data acquisition boards such as the National Instruments USB-6008
but also the programming of microcontrollers via platforms such as Arduino:
