Reduced graphene oxide enables stretchable strain sensor for monitoring of physical activities
A new work by scientists at India’s National Institute of Technology Rourkela describes the fabrication of extremely flexible, accurate, and robust strain sensors employing electrochemically produced reduced graphene oxide (rGO).
Conventional silicon-based strain sensors have relatively low flexibility of less than 5% and inadequate responsiveness, making them unsuitable for detecting both small and large strains. Aside from the flexibility constraint, typical silicon-based strain sensors need sophisticated manufacturing procedures such as microelectromechanical and deposition of thin films. Flexibility, responsiveness, and endurance are critical characteristics of wearable devices because they aid in the integration of the sensors over non-uniform interfaces such as the human body. Aside from elasticity, these products also need a sensor capable of detecting minute deformations caused by physiological factors and physical activity.
