Request for Proposal: Biomedical Device


Introduction and Overview

Biomedical engineering is an incredibly multidisciplinary STEM field that almost any engineering and computer science student can enter into. It is the application of biology and engineering to design new and innovative devices to improve healthcare and medical options. Some of the most well-known biomedical devices include artificial organs, prosthetics, wearables, and surgical robots.

Biomedical devices have already saved and improved the lives of countless people. Your goal will be to develop one of these devices. Your group is tasked with developing either a prosthetic or a wearable device that can improve the quality of life of the user. The prosthetic or wearable that you will develop will need to meet some basic requirements to be considered a working prototype.

Example Projects

Below are examples of potential BMD projects:

Bmd2.png
Bmd1.png
Bmd3.png
Bmd4.png

Specifications

Your team must design a biomedical device using the materials provided. An Arduino program that will direct the devices, sensors, and/or movements must be created. A cost estimate of the components of the device must be provided. All revisions to the original design must be recorded and explained. This includes technical design drawings, as well as cost estimates. All revisions to the Arduino program must be recorded and explained.

The biomedical device must be able to complete a predetermined series of tasks in a consistent and effective manner. The biomedical device options can be selected from the Device Choices list below. The device must also satisfy the following requirements:

  • Be an independent, self-powered device
  • Be one complete device (no loose or hanging components)
  • The device can complete all tasks autonomously
    • All outputs should be controlled by sensor/electric inputs
    • See the BMD Sensors Guide for help on how to use common BMD sensors
  • Use at least one machining method
  • The final device cannot include a breadboard

The device must be fully autonomous, and may not be altered or switched during any part of its use when Benchmarking and Commissioning. Please refer to the course syllabus for all due dates.

Device Choices

You must choose an option for your project out of the two given below:

  • Prosthetic Option: Develop an artificial limb, a piece of technology that can be worn and can effectively replace a lost body part. The artificial limb must contain features that replicate a hand, a wrist, and an elbow. However, only two of these features need to be fully functional. In order for a feature to be functional, it must be able to complete the following tasks:
    • The hand must be capable of wrapping around a shopping bag handle and lifting a 1 pound weight
    • The elbow must be able to move vertically at least 90 degrees
    • The wrist must be able to rotate at least 180 degrees.
  • Wearable Option: Develop a wearable device, a piece of technology that can be worn on the human body and provide valuable health or fitness information to the wearer. This device must be able to complete at least two of the following functions:
    • Measure/display UV intensity data and inform you of how long you can be exposed to that light intensity before it becomes harmful
    • Measure/display temperature data and inform you of how long you can be exposed to that temperature before it becomes harmful
    • Monitor/display your heart rate and warn you when your heart rate is becoming irregular
    • Measure/display gas data in the area and warn you if the air is hazardous
    • Display the current date and time

You can find the list of materials available for all BMD groups here:

Machining Methods

These are the machining methods that will count toward Benchmarking, Commissioning, and Extra Credit. Currently, EG1004 only offers 3D printing, while most other machining methods must be completed through the MakerSpace. For the MakerSpace machines, you must complete the MakerSpace Safety Orientation and sign-up for a training session to use these machines (MakerSpace training times can be viewed here). Some of these machining methods require extra materials that not all groups have access to.

  • 3D printing (plastics, available through EG1004, more filament types and build plate dimensions available through the MakerSpace)
    • This is an additive machining method, good for small and relatively complex 3D figures. More information can be found on the online MakerSpace 3D Printing Training (NYU Login is required to access training)
  • Laser cutting (wood or acrylic)
    • This is a subtractive machining method, good for precise cutting and engraving 2D figures. Laser cutting is particularly recommended for quickly manufacturing boxes. More information can be found on the online * MakerSpace Laser Cutting Training
  • CNC milling (wood, plastics, and soft metals, available in the MakerSpace)
    • This is a subtractive machining method, good for cutting and etching 2D or 3D shapes out of various materials. More information can be found on the online MakerSpace Othermill CNC Training.
  • Woodwork (hand and power saws available in the MakerSpace)

Microsoft Project

You must create a project schedule to manage your time in Microsoft Project. You can learn Microsoft Project by doing the MS Project Skill Builder. This schedule must include all tasks related to the project from the start of the project to Submission. Click here to access the guide on how to transfer a file. The Microsoft Project schedule should include the following:

  • Minimum of 20 tasks, excluding Milestones
  • Milestones should be clearly indicated on the project plan (duration of zero days)
  • Each task must include the person responsible for completing the task (resource names)
  • Use the "Copy Picture" function to include the project plan in the presentations. Do not take a screenshot
  • Gantt chart must be displayed alongside the tasks list (fit onto one slide)
  • Gantt chart must clearly show a progress line
  • Clearly state during the presentation whether the project is on-time, behind schedule, or ahead of schedule

For help planning the project, review the manual page Planning Project Scheduling & Costs.

Drawings

You will be required to draw a CAD model of your device for Milestone presentations and Benchmark assessments. You can use any CAD software to do so. EG1004 uses and teaches Fusion 360 for labs and other SLDPs, and Fusion 360 is the recommended software for CAD. You can download Fusion 360 for free using your NYU email. Other CAD software such as SolidWorks, Inventor, and Rhino are permitted, however EG1004 does not provide resources in obtaining or learning those programs.

Using your chosen CAD software, create four drawings of the device: front, top, most detailed side, and isometric. Sensors and motors must be included in each drawing.

Each revision of the design must be documented and all changes must be presented during Milestone presentations.

Figure 1: Example of BMD Drawing

Diagrams

You will also be required to create a circuit diagram and a schematic diagram of your device for Milestones, presentations, and Benchmark assessments. A circuit diagram visualizes a lifelike representation of your circuit, concerning the physical layout of the wires and how they're connected to the components. (Figure 2). A schematic diagram shows the plans and functions of your circuit, but is not concerned with the physical layout of the wires (Figure 3).

Figure 2: Circuit Diagram Example
Figure 3: Schematic Diagram Example

EG1004 recommends the circuitry modeling software Tinkercad and Fritzing to fulfill these deliverables. Tinkercad is a free browser-based circuitry software that is especially useful for constructing circuit diagrams with common electrical components. For projects with more complex electrical components, Fritzing is a free circuitry software with an encompassing library of electrical components that is useful for constructing circuit diagrams and schematic diagrams. For a guide on using both softwares, please refer to the Virtual Circuit Simulation Guide.

Cost Estimate

A cost estimate must be generated that specifies the cost of each component and labor required for the construction of the design. Tabulate this cost information clearly in an Excel spreadsheet. You should only use the materials currently held by EG1004 in the construction of your device. If you want to use other parts, get permission from your faculty member to do so. It is your responsibility to research and estimate the cost of all components used in the construction of the design. Help in calculating the cost is available by reviewing the Planning Project Scheduling & Costs page.

Create a cost estimate on a Microsoft Excel spreadsheet. The cost estimate should abide by the following specifications:

  • Labor cost breakdown with hours and rates
  • Consolidate low-cost pieces: wires, tape, servo motors
  • Itemize high-cost pieces: Arduino board, sensors, 3D printing filament, acrylic, wood
  • Total cost must be clearly shown in the bottom right corner


Engineering Notebook

While working on your project, you are expected to keep a record of all work done, as well as future plans and goals. In order to complete a Benchmark assessment, show your Engineering Notebook to the Open Lab TA completing your assessment. For Final Submission you must have it approved by an Open Lab TA in a Word Document (DOC or DOCX) format. A guide to writing the notebook, as well as a basic overview of its expectations and frequency at which you should log in your notebook, can be found on the Keeping an Engineering Notebook page.

Extra Tasks

Up to two of these tasks may be completed for extra credit. You have the freedom to decide which of these tasks you would like to complete.

  • Completing an additional Device Task
  • Completing Benchmark A, Benchmark B, or Submission early

Milestones, Benchmarks, and Deliverables

As you work on your project, you will be required to present periodic reports on your progress. We call these Milestones. All the items assigned in each Milestone are called deliverables. These deliverables often consist of a combination of written submissions, presentations, and demonstrations. Additionally, you will be required to meet certain assigned benchmarks, and hand in reports/deliverables that add to the progress and comprehensiveness of your project.The Prototyping Guide contains information on the 3D printing requirements and guidelines.

Note: You are only allowed to get a benchmark and commission approval from a TA for your project at the end of Lab or during Open Lab times.

Preliminary Design Investigation

The Preliminary Design Investigation (PDI) is extremely important, as it lays the groundwork for your project. You will be outlining your project idea, inspiration, and goals.

The PDI must include:

  • Cover Page
  • Project Overview
  • Goals & Objectives
  • Design & Approach
  • Cost Estimate
  • Project Schedule
  • Relevant Pictures

An example PDI template can be found here. The PDI is due Benchmark A and can be approved by any Open Lab TA. Do not forget to include the items listed above. Use this link to access the PDI Rubric.

Milestone 1

See How to Give a Milestone Presentation for the format of a Milestone presentation.

Milestone 1 should act as a presentation of your Preliminary Design Investigation. Without simply replicating your report in presentation format, take the key points to present in a concise and clear manner. The section formatting should be similar to that of the report. It is important that you outline your project goals and show that your project is realizable. This includes:

Milestone 1 Deliverables:

  • Presentation:
    • Project description
    • Design approach
    • Mission statement
    • Preliminary CAD drawing of device
    • Cost estimate
    • Microsoft Project schedule
      • Click here to access the guide on how to transfer a file
    • Progress update: current state of the project

You must decide your project goal from the Device Choices list for Milestone 1. You cannot change device choices after this deadline.
