As part of the early prototype development phase of ResQ, we designed and stitched the first basic overlay jacket after researching suitable design options, materials, and required components. A BB bladder was selected and used as the pressure bag in this initial model to support the intended compression-based mechanism.

In parallel with the mechanical development, the sensors planned for the system were tested to verify their suitability for the prototype. The test results showed that the sensors were performing as expected, giving us confidence in the selected sensing approach and confirming that the current component choices are appropriate for the next development stage.

With the basic jacket structure completed and the sensor behavior validated, our next plan is to assemble all components together and develop a working basic prototype model for further testing, refinement, and integration.

As part of the project's early-stage evaluation, the Proposal Presentation Session for Milestone 1 was conducted to present ResQ to Ms. Yasodha Vimukthi and Mr. Thilina Gunarathne. The session focused on validating the feasibility, clarity, and overall direction of the proposed solution. We discussed the motivation behind ResQ, its intended functionality, and its potential impact on CPR training.

The evaluators confirmed the relevance of the proposed idea and provided constructive feedback, particularly emphasizing the importance of budget feasibility and alignment with recognized CPR training standards. They also recommended engaging with resource persons from the Faculty of Allied Health Sciences to verify clinical requirements and clarify any additional needs.

Overall, the session was a valuable learning experience that strengthened our understanding of real-world constraints and expectations. The feedback received will guide further research, planning, and refinement of the ResQ system to ensure it is practical, standards-compliant, and technically robust.

This update presents our first practical prototype of the ResQ overlay jacket. We prepared a basic stitched structure and connected a manual pressure setup to observe how compression input behaves through the jacket layer.

The video focuses on three points: physical fit of the jacket, response of the pressure section during repeated compression, and overall stability of the setup for future sensor integration.

Based on these observations, the next phase is to mount sensing components, collect repeatable test readings, and finalize a more robust combined prototype for validation.
