Electronics Track Stroke Recovery With Flexible Stick On Sensors

Electronics in the form of flexible stick-on sensors can now effectively track post-stroke patients. They  keep working even when stretched and flexed repeatedly.




Electronics: Post-Stroke Monitoring And Diagnosis

At Northwestern University, John Rogers, the scientist responsible for many achievements in the field of flexible electronics has developed new sensors that stick directly to the skin. Placed on the throat, they measure vibrations produced by the vocal chords. They can help assess how patients swallow and identify unusual speech characteristics that may not be readily apparent.

The new sensors work with previously developed on-body sensors that Rogers and his team has created. These track the heart’s rhythm, muscle movement, and help with sleep analysis.

Post-stroke patients are tracked following a stroke, particularly those suffering from aphasia, a speech disorder. Currently, standing microphones and special software is used to assess speech. These are limited as they do not capture the nuances compared to a flexible stick on. The new throat sensors help create a detailed picture of the health parameters of stroke patients.



Flexible electronic sensors are a game changer insofar as stroke rehabilitation is concerned. The cordless sensors can monitor the patients anywhere. No longer do they need to be hooked up to a machine.

Here is  an informative video from the Shirley Ryan AbilityLab showing the latest electronic sensors used to monitor post-stroke patients:
