“…The creation of textile-based strain sensors has attracted researchers' attention, and hence many investigators are working this area and numerous different kinds of technique have been used in order to create strain-sensing structures [5][6][7]. Fang et al developed an electro-elastic dynamic model with surface/interface effect and investigated the electromechanical response of multilayer piezoelectric nano-cylinder under electro-elastic waves [8]. Gheibi et al fabricated Polyvinylidene fluoride (PVDF) nanofiber mat by electrospinning and showed that the developed mat can be used to convert mechanical energy to electrical power [9].…”

Textile-based body worn sensors are preferred due to its comfortability for continuous monitoring of the body vital signs and kinematics. This research discusses the development and characterization of elastomeric tape for strain sensor application and is used for the measurement of elbow angle. The stress strain properties of commercially available elastomeric tapes have been analyzed for the selection of suitable specifications of elastomeric tape. The actual sensor has been developed with the help of narrow width tape loom by introducing the silver-coated nylon yarn in the middle of the tape structure. The effect of linear density of conductive yarn and number and strands of conductive threads used on sensitivity of the sensor was studied. The repeatability of the developed sensor was characterized by cyclic testing using Zwick tensile tester. Based on the results, polyester yarns were used as base threads along with rubber threads for the sensor development. It was found that sensor developed using finer yarn with six conductive threads has higher sensitivity. The developed sensor was integrated on to elbow sleeve and elbow angle measurement was done. The results of the developed tape sensor have been compared with the hospital goniometer for 10 male subjects. The results showed that the developed tape sensor is suitable for measuring the elbow angles up to 150°.

An analytical model is proposed to predict the electromechanical response of anisotropic piezoelectric composites containing spherical piezoelectric nano-inclusions under a uniform electric field. The electroelastic surface/interface theory for nano-size structures is introduced to analyze the nano-size effect. The analytical solutions for the elastic displacements and electric potentials in the nano-composites are derived exactly with consideration of the elasticity, permittivity and piezoelectricity of the interface. The unknown coefficients are determined by satisfying the boundary conditions with interface effect. Numerical examples show that the elasticity, permittivity and piezoelectricity of surface/interface express different effects on the stress and electric displacement in the nano-particle and matrix. The jump of stress and electric displacement under different material properties of the interface is also examined.
