Job Description

A viable candidate will contribute to development, reiteration and testing the HeartWatch System closely with the engineering team. This includes comparison testing existing solutions, innovating ways to improve sensor quality and working with the implementation of the novel sensor developed in-house for the HelpWear system. The candidate will also be a core member of the design and engineering team, where they will help address problems in both areas.

Things That You Might Need to Know

- C coding language for firmware development- Understanding of documentation and engineering design process implementation

- Java/Android for in app implementation

- PCB designing and layouts

Things You Must Learn

- Operations of a ECG

- Operations of a Capacitive ECG electrode

- Documentation structure

- Bench testing and key test points to identify

Things You Must Learn

In the HelpWear system, the EPIC sensor is used, the epic sensor being used is called the PS25255. The important thing to understand is that the EPIC sensor does not compute how the ECG should look rather it collects the signal itself. The EPIC sensor is classified as a capacitive sensor. This can mean a lot of things. The way that the system leverages the EPIC sensor is by pulling signals from the body and correlating that with the correct time to calculate the ECG signal. This is the core functionality of the device. One concept that can either make or break the device concept is the grounding ability of the device. The individual nodes need to agree on one key concept, they need to have the same ground. The only way that this can be achieved in this setting is if we use the user's body to make that ground. Now, this may not be possible where we can use the human body as a wire to connect the system to ground. In that case, there might be an issue where grounding the system to the user might cause for more noise being that we would be harming the system noise-free environment, not to mention is the user is grounded to earth that might have a far greater effect. We are open all ears to a solution.
