BN3101: Biomedical Engineering Design

Module Description :

Preparation of formal engineering reports on a series of engineering analysis and design problems illustrating methodology from various branches of applied mechanics as applied to bioengineering problems. Statistical analysis. A term project and oral presentation are required. Students are exposed to the entire design process: design problem definition, generation of a design specification, documentation, design review process, prototype fabrication, testing and calibration.

Note: Lecture to be conducted online. Students need to go through the lecture notes each week before attending tutorials.

Please submit soft copy of your report & project data and actual prototype to your respective supervisor. That is:

  • Physically: submit project prototype (including tools borrowed, make also sure the prototype is functional at the time of your submission.) to Dr. Ren
  • Electronically: (dropbox/google-drive or whatever ways preferred) submit to Dr. Ren your group-project development documents including:
    • – reports in .docx format
    • – project presentation files (ASTM and final) in .pptx or equivalents (please make sure the video(s) is playable in another PC if applicable);
    • – CAD design files (in solidworks or equivalents)
    • – if applicable, source codes and a readme file on how to run the code
    • – other key project data (e.g., verification experiment data collected in .xlxs), references including ASTM standards, patents cited, and reference papers, etc.

Further possibilities

Possibility of investing your project and extend it to competitions (Completely voluntary and please discuss with Dr. Ren if for possible further extensions/supports/funding):

  • A manuscript to IJRA or MBEC
  • Samsung Solve For Tomorrow Competition http://www.samsung.com/sg/solvefortomorrow/
  • The Design of Medical Devices Conference call for 2-page technical brief (by Nov. 9, pretty easy to get accepted and it can be just a summary of your group project). You only need to follow “the required Technical Brief Template (Word)” (2-page) and get my comments before submission. The benefit is that “All accepted papers will be published as a two-page Technical Brief in the June and September issues of ASME Journal of Medical Devices” after giving the conference presentations and this would be a pretty good record in your CV when you are looking for jobs.

IVLE: BN3101: Peer Assessment 2014

Dear BN3101 Students,The peer assessment exercise is conducted for students to assess their group members’ individual contribution to the project. For each review item you can grade your fellow group members from 0 to 10 by following a general marking standard of:0 = extremely poor;
6 = average;
8 = good;
10 = excellent.To do the peer assessment, please follow the steps of: go to the BN3101 IVLE webpage –> click Project –> click View –> click Project Evaluation (on the left) –> Select Peer Assessment 2014 –> click  Evaluate –> Evaluate your other group members one by one.Please do not routinely assign a high score as this will result in an average score for everyone. For this to work you have to give an honest assessment of your peers. The purpose of the peer assessment is to make minor adjustment within the group.
Your peer assessment rating will not affect other groups. And the rating by individual students is confidential and will not be made known to other group members.
Please complete the Peer Assessment 2014 by 14th Nov 2014 (Friday), 11:59pm; failure to do so, your group members’ project marks based on “team effort” will be affected.
Regards,
Aneel Kumar

BN3101 booking of machines in the design studio

Dear BN3101 supervisors,This semester both BN3101 and BN2103 will be using the Design Studio.To avoid problems, we set up an online booking system accessible (within NUS or VPN) at:http://172.18.53.85/bmebooking/
This applies to all the “workshop” machines in the lab like mill, lathe, saw, etc (not the Instron).
Please let your students know that if they want guaranteed time on the machine they will need to book. Students who booked the machine will have top priority in using the machine during the booked time slot.
The following restrictions on bookings apply (the system automatically detects violations of the rules ):
– Each single booking can last no more than 2 hours
– Each student can book a maximum of 4 hours per week per machine
Each BN3101 group will have an account with username BN3101_X (where X is the group number). Password is the same as the user name. Students may change it from the system later if they want to.
Kindly contact with Aneel, so he can creates the account for your groups.
Regards,
Dr. Leo
