Reference number : GC-2017-Q4-00976, amendment number : , agreement type : G, recipient legal name : Lai, Yongjun (Queen’s University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Flexible wearable sensors have found increasing application in many situations, especially in biomedical_x000D_
engineering and health care. Recent research has presented methods for fabricating flexible, stretchable, and_x000D_
conductive sensors using silver nanowires embedded in a flexible silicon elastomer (typically_x000D_
polydimethylsiloxane (PDMS)). In such a way, PDMS and nanowires have great potential for developing_x000D_
wearable sensors, based on capacitance or resistance changes, which can be used to many applications, such as,_x000D_
dry electrodes for ECG (electrocardiograph). However, in-depth understanding of the correlation between_x000D_
fabrication process and mechanical and electrical properties of the formed flexible sensor, such as, surface_x000D_
adhesion, stiffness, sensitivity, impedance, still need to be discovered before this technology can be used more_x000D_
widely._x000D_
In this project, we will investigate how the fabrication parameters affect the properties (mechanical and_x000D_
electrical) and desired sensing performance of formed PDMS and nanowire electrodes, as wearable sensors._x000D_
Comprehensive understanding obtained from this project will enable the creation of dry electrodes for ECG_x000D_
application, which could resolve the current limitations such as high skin-electrode impedance and artifacts_x000D_
caused by relative skin-electrode motion. Consequently it becomes an alternative for current wet electrodes, the_x000D_
standard for capturing physiological electrical signals in clinical use. Such wet electrodes are silver-silver_x000D_
chloride (Ag-AgCl) based and require conductive gel, which introduce patient discomfort and are unsuitable_x000D_
for regular long-term use._x000D_
Success of this project will provide comprehensive understanding of the correlation between fabrication_x000D_
parameters and properties and the performance of PDMS and nanowire sensors, and pave the way for our_x000D_
industrial partner to produce desirable dry electrodes for ECG, which will potentially improve health care_x000D_
quality and reduce cost for Canadians., program purpose french : Flexible wearable sensors have found increasing application in many situations, especially in biomedical_x000D_
