Photoplethysmography
Service-Learning Project 

This was a Service-Learning Group Project I had in my Year 2, April 2021 semester. During this Service-learning project, we came up with a photoplethysmography circuit and prototype for construction workers, in hopes of reducing the number of workplace incidents. An interview was arranged between a group of injured construction workers and us students, for us to get to know them and their situation. 

​

For this project, we had to come up with a practical circuit, build the actual circuit, a software circuit on Altium, and also a casing for the prototype. As such, we were taught the steps to plan a project and how a project can be effectively distributed within a group. 

​

I have learned a great deal through this project. It has equipped me with skills such as soldering, effective researching, project planning, time management and communication. Having to use Altium software for advanced circuit connections has also developed me as an engineer as it educated me on how to efficiently construct and develop different PCB designs, which is an extremely vital factor in engineering. As a result of building a casing for the prototype, I have also gained knowledge of 3D designs and the various factors that go into designing a prototype.

​

Through this project, I understood the importance of open communication with stakeholders and groupmates, and to also to be open-minded in every situation. Moreover, I have learned that when working in the healthcare and engineering industries, it is essential to empathize and have critical thinking skills to provide stakeholders with the best quality of work.
