Multifunctional and stretchable graphene/textile composite sensor for human motion monitoring

Sensors based on electronic textiles (e-textiles) have become increasingly prominent in the field of biomechanical monitoring technology due to multiple properties such as being lightweight, flexible, and comfortable, with increasing potential incorporating into long-term devices. Previous research has been conducted textile strain sensors graphene for human motion monitoring, however most e-textile exhibit poor sensitivity stretchability. To our knowledge, no previous looked at knitted graphene-based fabrics regards fabric composition substrate. In this paper, we propose a graphene/fabric composite sensor using cost-effective dip coating method an acrylic/Spandex knit fabric, further explores its mechanical, electrical, sensing properties. The developed graphene/textile wide range (up 344%) exhibits good high gauge factor up 16. As wearable sensor, can detect both large subtle motions is able distinguish between various ranges joint movements, demonstrating ability function system. Our be used supercapacitor or capacitive pressure sensor.
