Principles of Biomedical Instrumentation Final Project
Business Touch
To be honest, we didn’t have the right materials or a fan small enough to make everything work the way we imagined. At first, that felt like a failure, but then I started thinking about how design itself could fill the gap. That’s when the Blue Jay came to mind. It’s the symbol of our university, and shaping the mask like its beak made the whole thing feel alive, not just functional. Even though our prototype only proved the concept, adding that bit of identity and beauty made it feel more like a real product - something people might actually want to wear.
Motivation: Designed for healthcare workers, industrial laborers, and users in humid climates who require long-term mask use but experience discomfort from moisture and heat buildup.
Design:
Humidity Regulation System
Real-time monitoring with DHT11 sensors and Bluetooth connectivity.
Active fan-driven airflow triggered when humidity exceeds a set threshold.
Disposable desiccant chambers provide passive moisture control.
Users can view and adjust humidity thresholds through a mobile interface for a personalized experience.
2. “Blue Jay”-Inspired Aesthetics
A beak-shaped front enhances airflow and comfort while serving as a design symbol of protection and clarity.
Integrates function and fashion, reimagining the traditional mask as a wearable tech accessory.
3. Modular Lightweight Construction
Swappable desiccant units for different climates.
Compact electronics embedded without affecting wearability.
