A low-cost, portable EMG device using a Raspberry Pico and Myoware module can reliably measure muscle activity and fatigue during isometric and isotonic contractions, comparable to research-grade equipment.
Sensors · 2023
Key Findings
- 01Strong congruence between the low-cost and research-grade EMG devices for isometric contractions, with no significant difference in detecting muscle fatigue.
- 02The low-cost device showed similar behavior to the professional device in 70.58% of cases during isotonic contractions, though it was more susceptible to noise and movement artifacts.
Application
Design takeaway
Designers can leverage affordable microcontrollers and sensor modules to create effective physiological monitoring tools for ergonomic assessments in the field.
How to apply

Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Direct comparison with a research-grade device provides strong validation.
- +Inclusion of both isometric and isotonic contractions covers different types of muscle activity.
Limitations
Your own low-cost EMG setup might be more susceptible to noise than even this study's device, especially if not properly shielded or if movement artifacts are significant.
Reliability & validity
The study's validity is supported by the direct comparison with a gold-standard research-grade EMG device. Reliability is suggested by the consistent findings for isometric contractions, though the moderate success rate for isotonic contractions indicates potential variability.
Think critically
To what extent can the findings from controlled laboratory settings (like this study) be directly applied to the unpredictable and dynamic conditions of real-world field work, especially considering the noted susceptibility to noise and movement?
Design Principles
"Accessibility and affordability in physiological monitoring tools can democratize ergonomic assessment and improve worker safety."
This development offers a practical and affordable solution for monitoring the physiological strain on workers in real-world settings. Understanding muscle fatigue is crucial for designing safer work environments and preventing injuries, directly impacting worker well-being and productivity.
What This Means for Your Design
You can build a cheap device that's almost as good as a super expensive one for checking if people's muscles are getting tired at work.
How to use in your project
- 1.Use this as a case study to justify the selection of a low-cost sensor for your own project, demonstrating an understanding of trade-offs between cost and performance.
- 2.Reference the findings when discussing the importance of physiological data in user research.
