GITD, Glow In The Dark is your CPR confidence-enhancing wearable. It's a beacon in emergencies, boosting confidence when real situations arise. The design provides real-time, step-by-step guidance, removing hesitation and dependency on others. Its tailored features ensure decisive action based on your training. Adapting to personal preferences, it's easily carried—on a bag, a keychain, or in a pocket—always ready to guide you during critical life-saving moments, making a significant impact when every second counts.

The idea behind this design stemmed from observing hesitation in emergency scenarios requiring cardiopulmonary resuscitation, also known as CPR. Our goal was to diminish this hesitancy, encouraging swift intervention. Drawing from CPR training methods and tech advancements, this design was conceived to provide real-time, step-by-step guidance, instilling confidence in aid delivery during emergencies.

Potential Users:

We designed for people who have received CPR training but are not confident enough to come forward to practice CPR in the face of emergencies, so they can help others in times of emergencies with the aid of our products.

Uniqueness of the design:

The design provides real-time, step-by-step guidance, removing hesitation and dependency on others. Its tailored features ensure decisive action based on your training. Adapting to personal preferences, it's easily carried—on a bag, a keychain, or in a pocket—always ready to guide you during critical life-saving moments, making a significant impact when every second counts.

Design details:

Upon donning this product during CPR, the pressure applied is captured by the sensor, converting it to a light indicator on the back of the hand strap, allowing an intuitive assessment of whether the applied pressure is adequate (either too light or too heavy), as well as the count of cardiopulmonary compressions administered. Concurrently, the device emits a drumbeat audio at a rate of 80 beats per minute, assisting the rescuer in maintaining a consistent compression rhythm to ensure stability in the rescue efforts.

Research:

We utilized FlexiForce pressure sensors to measure compression depth in CPR, conducting 50 tests. Based on these tests and the sensor's sensitivity, we optimized the control software and packaging materials to achieve accurate depth detection within a critical 0.5-0.6 second interval, while also reducing electrical noise. Our research validated the technical feasibility of the designed device, highlighting the significance of sensor applications in healthcare and the importance of precision in life-saving techniques. It demonstrated that our design approach could provide ideal monitoring during CPR, showing significant potential for practical application.

Technology Employed:

The wearable device is meticulously engineered, comprising two ergonomic silicone pieces housing pressure and touch sensors, alongside a self-adjusting mechanism catering to varying hand sizes. The strips, crafted from breathable sport mesh, discreetly encapsulate LED modules on the upper part, providing tangible light feedback. The confluence of robust materials and sophisticated sensor technology fosters a real-time interactive experience for the user. Through iterative design methodologies and leveraging advanced production technologies, this design transcends as a marriage of functionality, user-centric ergonomics, and immediate visual feedback, quintessential for effective CPR administration

Challenge in the Process:

Designing a CPR-assistance device demands a careful balance between intuitive use in critical scenarios and providing supportive, effective aid. Key to this device is a pressure sensor linked with a visual feedback mechanism, alongside a versatile 'lacing' system tailored for various hand sizes to be put on easily and efficiently.
