BE Design Project Ideas (Version 2.1)

Dr. C. S. Tritt

Last updated: December 12, 2000

 

The following is a list of possible projects for the 00yyx B.E. design groups. Please write your cover letter to apply for a specific position (GM, PM, APM or Engineer) and to a specific project. Keep in mind, however, that only about 5 of these projects will be assigned to this year’s class and that assignments will be made based primarily on the needs of groups, not the desires of individuals.

 


 

1.                 Home Healthcare Device

 

Sponsor: Drs. Gassert & Canino and possibly a specific device company

 

Identify a specific opportunity and develop a medical device for use in the home.

 


 

2.                Medical Products for Developing Markets (Poor Countries)

 

Sponsor: Dr. Tritt (I have a contact in Romania) and possibly the U.N. or other agency

 

Identify a specific medical device opportunity in a specific developing market. A major challenge will be to identify local needs and economically viable options.

 


 

3.                Follow On Project – This Year’s Seniors

 

Sponsor: Drs. Lisa Milkowski and Mary Louise Brown

 

Follow up on one of this year’s senior design projects. Students would get to choose the project they follow up (with faculty approval). One possibility in this area is a clinical (biological signal) database to device front panel system. This device would retrieve biological signals stored in a PC database and output them (via an analog signal or signals) to commercial medical equipment. This device would be used as a teaching aid in the nursing program.


4.                Follow On Project – Last Year’s Seniors

 

Sponsor: Vince Canino

 

Follow up on one of last year’s senior design projects. Students would get to choose project they follow up (with faculty approval). One possibility includes a photometric pulse oximetry simulator. This device would provide a light (visible and possibly near IR) input signal to a commercial pulse oximetry system. It would be used as a teaching aid in the nursing program.

 


 

5.                Coordination Performance Tester

 

Sponsor: C. S. Tritt

 

Design a device that tests human eye-brain-hand coordination. The intent of this device would be to detect performance deficits (due to alcohol, drugs, sleep deprivation or illness). The device would have to be low cost and self-contained (not PC based). It would be based on the latest literature, codes and laws regarding human performance and intoxication.

 


 

6.                MRI Phantom

 

Sponsor: Kevin Bennett, Medical College of Wisconsin

 

Mr. Bennett (an MSOE graduate) writes:

 

We are studying diffusion processes in neural systems, that is , parynchema and vasculature. My main interest is in bound-compartment contributions to MR signal decrease with diffusion-weighted pulse sequences. The project would be to design a phantom for MR which would contain capillaries on the order of microvasculature, the permeability of which could be adjusted somehow (electrically?), and the orientation of which could be precisely specified. This is sort of an NMR rather than imaging project, but would probably lead to a patent if it worked. We're working on one for our studies now, but it doesn't have all the features of the one I just mentioned.

 

If you have any students who might be interested in a project like this, please let me know. I would be happy to talk to them. I think it would be ideal for students interested in getting a few publications or research experience before they graduate (obviously they would be included in any papers regarding the phantom).

 

7.                Thermal Therapy Device

 

Sponsor: Dr. Tritt & possibly Gorix.

 

Develop a thermal therapy or other heat generation and transfer related medical product. Gorix is company that produces an electrically conductive fabric. They are interested in finding applications for their material. Students would identify a specific medial need related to thermal therapy and design a product to meet this need.

 


 

8.                Depth of Anesthesia Monitor

 

Sponsor: Dr. Tritt

 

Develop a device to monitor the depth of anesthesia during surgery. Device could be based on digital analysis (Digital Signal Processes or DSP) of EEG data or some other method.

 


 

9.                Commercial Software Tools for Biomedical Engineering Fluid Mechanics

 

Sponsor: Dr. Tritt

 

Evaluate commercial fluid flow modeling software for use in biomedical engineering products. Determine if any current products are applicable and, if not, what additional features would be needed. The flow actually modeled would be up to students with faculty approval. Possible flows include those at the carotid bifurcation or in an artificial heart valve. The result of this project would be the flow analysis model and a software guide geared specifically to biomedical problem solving.

 


 

10.           Use of Rapid Prototyping in Biomedicine

 

Sponsors: Drs. Tritt & Milkowski

 

Identify and explore opportunities for the application of rapid prototyping technology in biomedical engineering, possibly following up on an existing REU/RPC project.


11.           Biomedical Application of Microelectromechanical Systems (MEMS)

 

Sponsors: Drs. Tritt & Milkowski and Douglas Kerns, Sierra Madre, CA

 

Possibilities suggested by Mr. Kerns include:

 

Identify and explore opportunities for the application of microelectromechanical system in medical devices. Custom IC design to do transmissive optical plethysmography (check out the MOSIS service for cheap IC fabrication). Integrate the photodiode pickup, preamp, and filtering stages on one chip. An aggressive design project could also integrate an ADC and an LED driver, so that the thing could become nearly a complete digital-output instrument.

 

Any of an assortment of possible catheter-tip sensor types e wedged into a slight modification of an IC fabrication process.

 


 

12.           Biomedical Application of Microfluidic Systems

 

Sponsors: Drs. Tritt & Milkowski and Douglas Kerns, Sierra Madre, CA

 

Identify and explore opportunities for the application of microfluidic systems in medical devices. Mr. Kerns suggests a custom IC, micro-machined hotwire anemometer for catheter-tip measurements.

 


 

13.           Improved Wet Chemistry Technique

 

Sponsors: Dr. Tritt & Leo Roemer, Denmark

 

Many medical tests still involve wet chemistry (manual mixing of multiple reagent solutions). The sponsor of this project writes:

 

One of the items we offer is a test for Streptococcus A. Are you familiar with that type of test device? It works in this way:

 

You add two drops of two different reagents into a small well. Afterwards you take a swab and rub the patients throat (to get the bacteria on to it) and then you put the swab into the well and leave it for a couple of minutes to extract. You then press the swab gently, and the bottom opens and the fluid flows along a test strip towards a result window.

 

The problem with this type of tests is, that the different reagents should not be mixed until immediately before use - and it is a point of irritation for the doctor/clinician to have to apply the drops. It takes time and there is a risk of mistakes being done.

 

And now my suggestion: How about designing a device where the different reagents are already in the well, covered with a foil - each reagent "stored" in membranes of some sort - thus you just have to take the swab and pierce the covering foil and the membranes - this would make the test a real one step test instead of the 4 or 5 step "one step tests" currently on the market.

 

The device should also be capable of storing a tablet of some drying compound - I don't think it is silica gel. And some devices have a small window turning to a different color when the fluid hits it, indicating that time is up for reading the result.

 


 

14.           Device Controller for Quadaplegics

 

Sponsors: Dr. Tritt & Douglas Kerns, Sierra Madre, CA

 

Students would specify and design a device that could be used by quadapledics to control laser pointers (or other items, like PC mice). The basic function would involve determination of where the user was looking. Such a device could be based on the electro-oculargram or some method identified by the students.

 


 

15.           Short Range Medical Telemetry System

 

Sponsors: Dr. Tritt & Douglas Kerns, Sierra Madre, CA

 

Develop a short-range medical telemetry transmission system (RF, IR or acoustic). Possibly, use one of the new short-range wireless digital standards (like Bluetooth, etc.). This would allow students to use off the shelf hardware and concentrate on biomedical specific software issues such as reliability and security.


16.           A Biomedical Application for Virtual-Reality (VR) or Tele-Presence (TP)

 

Sponsors: Dr. Tritt and Douglas Kerns, Sierra Madre, CA

 

There have been a number of biomedical applications suggested for VR and TP technology. This design project would involve selecting a specific application and developing a VR or TP system for it. Mr. Kerns writes with the following suggestions:

 

Electro-myogram (EMG) controls for virtual-reality or games.

 

EMG pickup array (and probably other electromagnetic sensors) combined with animation software to display subject body postures and motions.

 

Simple force-feedback data glove for a remote actuator.

 

Tactile/haptic actuators for virtual-reality or game controls feedback.
