General Design Requirements and Ergonomic Considerations
General Design Requirements and Ergonomic Considerations
Teams must design and build a wearable device that can monitor the respiration rate of an infant. The device must be:
designed so an adult caretaker can tell how many breaths a baby takes in one minute by looking at a “data transmitter” (i.e., a blinking LED).
suitable for use on a baby (i.e., would not cause discomfort or injury to a baby).
easily placed on and removed from a baby.
adjustable so it can fit on different sizes of babies.
able to stay in place and continue monitoring breathing during normal baby movements like squirming, rolling, and being lifted by a caregiver.
durable and reusable.
aesthetically pleasing.
Technical Requirements
Technical Requirements
The final design of the wearable device must meet certain requirements. The device must:
use a switch to sense chest movements when a baby breathes.
There are no restrictions or specific requirements for the type of switch that can be used. The switch can be made by the team, taken out of a different device, or purchased.
indicate on a “data transmitter” each time the baby takes a breath.
The data transmitter is an LED located at least 27 inches (70cm) from the baby. This allows the data transmitter to be placed outside of a crib or hospital bed while the baby is sleeping. The LED must light up each time the baby takes a breath. An adult caretaker can count how many times the LED lights up in one minute to get the respiration rate.
be powered by battery. An adult caretaker must be able to easily change or charge the batteries.
Materials Requirements
Materials Requirements
When selecting materials for this project, teams should consider that the device is designed to be placed on a baby and to be used by parents, childcare providers, and medical professionals. The device:
must be made of materials that are appropriate for use on a baby’s body.
There are no restrictions or specific materials requirements. However, materials used in the device should not have the potential to cause discomfort or injury to a baby. Teams are not required to use and are not limited to the materials in the starter kit provided by Maryland MESA.
must cost no more than $30 to build.
Materials provided by Maryland MESA do not count toward the $30 spending limit. All materials used should be recorded on an itemized budget sheet. For more information, please see the Expense Report Guidelines later in this document.
Design Bonus
Design Bonus
Teams will receive bonus points for devices that are exceptionally well designed and built and/or demonstrate excellent consideration of human factors (i.e., ergonomics).
Testing and Demonstrating the Device
Testing and Demonstrating the Device
Each MESA club has been provided with a NeoNatalie manikin. The chest of the infant-sized manikin moves in a way that mimics respiration. This makes it the ideal testing device for prototypes developed for this challenge. The team should use a NeoNatalie manikin to test and demonstrate their prototype. However, if a team does not have access to a NeoNatalie manikin, they can use another object to test and demonstrate their prototype. A simple, low cost test device can be created using items typically found in many homes. For instance, a football, balloon, or baby doll could be used to represent an infant’s chest. Finger or hand movements could be used to simulate chest movements. The testing device does not need to be complicated. It simply needs to be able to help the team develop and demonstrate a device that fits on an infant’s chest and senses motion of the chest.
The type of device used to test and demonstrate the prototype will not have an impact on scoring. In other words, the team will not be penalized if they do not have access to a NeoNatalie manikin and must create their own test device.
IMPORTANT NOTE ABOUT SAFETY:
IMPORTANT NOTE ABOUT SAFETY:
All testing should be conducted on NeoNatalie manikins or on other testing devices.
All testing should be conducted on NeoNatalie manikins or on other testing devices.
No testing should be conducted on humans or animals.
No testing should be conducted on humans or animals.
Judging
Judging
During this project, the team will focus on designing a device that can be used to monitor and accurately report the respiration rate of an infant.
Teams will demonstrate the accuracy of their device. Because each team will demonstrate their device in a different environment with different equipment (e.g., testing devices), and because judges will not be present, it is not possible to ensure that the accuracy of the device will be correctly reported by teams. Therefore, the actual accuracy of the device will not be used to rank entries in the competition. A video-recorded presentation and electronic display board about each team’s design process and final solution will be used to score projects.
Projects will be scored in the following categories:
Video-Recorded Presentation and Demonstration (video submission) 100 points
Electronic Display Board (.pptx file submission) 60 points
Design of Device 40 points
If a design/device does not perform as well as the team would like, the team is still encouraged to submit a video-recorded presentation and electronic display board. The presentation and display board can showcase the process the team used, even if the device does not work properly.
Please refer to the guidelines below and the scoring sheets at the end of this document for details about judging criteria.

(video submission)
(video submission)
The team must deliver a video-recorded presentation that describes their design process and their final design. The presentation, including demonstration, can be a maximum of 10 minutes in duration. Creativity is encouraged. The team must address the following during the presentation:
Introduction of Team Members/Description of Roles
Background Information
What background research did the team do related to this challenge?
Design and Development Process
How did the team test different designs?
What improvements did the team make to the design during the project?
What obstacles did the team face while working on this project? How did the team overcome those obstacles?
Description of Design
What are the important parts of the design? In other words, describe the final design.
Does the team’s solution meet all design requirements?
The video must clearly show that the device meets the requirements.
How do the switch, wires, and LED work together to monitor and report respiration?
How did human factors/ergonomics considerations impact the design (e.g., materials, design of device, fastening methods, aesthetics, etc.)
Demonstration
Describe and demonstrate how the device is used.
(Hint: Think about how you would teach a parent or caregiver to use the device.)
Demonstrate how an adult would place the device on an infant.
Evaluation of Effectiveness of the Solution
Does the device accurately report respiration rate?
The video must show the LED lighting to show breaths.
What parts of the device work well?
