| 内容記述 | The last decade has witnessed a shift in the research trends from hard and brittle to soft, flexible, and lightweight wearable devices. There is a fast-growing demand for wearable strain sensors amongst all existing electromechanical soft devices, due to their potential applications in areas like wearable electronics, soft robotics, human motion detection, fitness industries, rehabilitation, and human activity monitoring. Stretchability, sensitivity, life, and repeatability in the wide range are highly desirable for strain sensors. In order to achieve this goal electroactive polymer （EAP） based capacitive strain sensors have been explored as one of the potential candidates for their application in the area of wearable devices. An electronic type EAP-based strain sensor was fabricated by using silver-coated conductive fabric as an electrode and mixture of silicone rubber as a dielectric film. This sensor was showing linear behaviour but low capacitive range （pF） and less elasticity due to fabric electrode restrict its use in a wide range of applications. To overcome this problem Ionic type of EAP-based strain sensor was fabricated, and efforts were directed to prepare free-standing stretchable polymer films to make capacitance strain sensors while introducing conducting polymers to make hybrid films with controlled conductivity and carbon grease was used as an electrode. It was found that conducting composite film-based strain sensor can sustain millions of stretching and relaxing cycles, showing high linearity, negligible losses, very high stretchability, and sensitivity. Hyperelastic and viscoelastic modeling have been conducted for estimating different material losses. A crack growth approach has been proposed for predicting the life of the sensor. Complete electromechanical modeling has been proposed for analyzing sensor behavior in 3D space. Further uniaxial tensile testing data was used to estimate different material constants and for predicting sensor behavior in multiaxial loading. Open and fist hand gesture was also recognized. | |||||||
