Features

Our project's main objective for this project is to create a portable device for which it can capture bio-signals and be able to independently alert the user indications of anxiety based on the captured signals and help with the subsequent relaxation needed.​Stress reduction of the user is the main motivation of the project, since we are aiming to build a system that will monitor and remind the user to take a momentarily break.

Portable

Lightweight design has the potential to be a dependable wearable. Easy to carry around and small enough to use all day.

Power Efficient

Battery operated device communicating through Bluetooth Low Energy for power efficiency.

Easy Data Analysis

Sleek and simple app design to easily view biosignal data and notify user when stress levels are detected.

Project Timeline

When everything came together

  • AUG 2019

    Formation of the Team and Project Selection

    Team of 4 came together with 2 CPEs and 2 EEs. It took a couple of weeks to brainstorm ideas, started with about 50 ideas and narrowed down to 1 idea -- a biofeedback device as a stress monitor tool.

  • DEC 2019

    Preliminary Component Selection and Design

    In between the months, each members start selecting components for the hardware design that fit the engineering requirements and specifications. By the end of the semester, the sensor boards has been shipped for manufacturing. Our first revision for the heart rate sensor and other sensor boards are completed.

  • FEB 2020

    Testing Break Out Boards and Modules

    The first revision of the sensor boards and the power module has gone through functional tests as they arrive from manufacturing and assembled each by hand.

  • APR 2020

    Final Integration and Completion

    After the boards have been tested separately and our components have been updated yield better results that are closer our engineering requirements and specifications. Final board revision has been created in order to be sent to manufacturing. Our software app has been conceptualized and rapidly developed and built with Android studio. Amidst the COVID-19 situation, our team has managed to properly integrate our breakout boards and end with a functional device.
