Highly wearable galvanic skin response sensor using flexible and conductive polymer foam

Area of Science:

• Biomedical Engineering
• Wearable Technology
• Physiological Monitoring

Background:

• Advancements in daily physiological monitoring technology enable new healthcare applications.
• Monitoring skin conductance responses (GSR) shows potential for detecting emotional changes.
• Existing GSR sensors may lack wearability and ease of use for continuous monitoring.

Purpose of the Study:

• To propose a highly wearable and reliable galvanic skin response (GSR) sensor.
• To develop a GSR sensor attachable to clothing for enhanced usability.
• To validate the sensing reliability of the proposed back-mounted GSR sensor.

Main Methods:

• Utilized flexible conductive foam as the sensing material for enhanced wearability.
• Designed the sensor for easy attachment and detachment from various clothing items.
• Evaluated sensor reliability by comparing its signals with a reference GSR device.

Main Results:

• The proposed GSR sensor demonstrated high wearability and usability.
• The sensor achieved an average signal correlation of 0.768 when compared to a reference GSR.
• This correlation validates the sensor's feasibility for reliable GSR sensing on the back.

Conclusions:

• The developed wearable GSR sensor is reliable for physiological monitoring.
• The sensor's design enhances user comfort and practical application in healthcare.
• This technology supports diverse healthcare applications, including emotion detection through physiological signals.
