About the Company: 

HelpWear is striving to achieve better at-home healthcare by developing affordable and accessible products for patients all around the world. HelpWear is currently developing HeartWatch, a 24/7 wearable heart monitoring system with an embedded emergency contact system for furthered prevention and better treatment of heart-related illness. Since our founding in the summer of 2015 in Ryerson University’s Basecamp program, HelpWear has grown to operate in Ryerson University’s Zone network, the University of British Columbia through CDL West, the Y-Combinator Accelerator program, and the Waterloo region.

Project Description:

In a (normal) wired ECG a differential signal is created between two sensing devices. A reference potential (typically a ground plane) is used by electrically connecting the two sensor ground by a wire. To develop a wireless ECG sensor, this grounding wired connect is removed, thus removing the ability to find a reference potential on each individual sensing device. This causes for the ground of one device in comparison to the ground of a second device to be unknown and constantly floating (this makes the signal more difficult to acquire at the required accuracy). 

Research Objectives:​

  • Assessment of different methods that can be employed to solve or reduce the severity of the problem (mentioned above)
  • Designing simulations or test benches around testing possible solutions
  • Prototyping of potential solution to the problem


  • Usually starts off with literature research unless already known topic based on person working on project
  • Review of different approaches to tackle problem
  • Simulation modeling
  • Breadboard and PCB prototyping
  • Assessment of prototype against a classical holter through comparing outputted ECGs via software

Expertise and Skills Needed:

  • Understanding of Electrical engineering and circuits
  • Understanding of ECG would be asset
  • Experience with micro electronics
  • Experience with Matlab and signals processing
