With the dramatic technological growth of wearable electronics, the demand for increasing the high mechanical-electronic capabilities for new applications has increased. Although the existing devices have limited stretchability, flexibility and compliance, these capabilities are not enough and the development of conductive materials with high elasticity and greater sensitivity to withstand high strain or pressure is required. In this research, some resistive strain gauges are developed with various properties such as flexibility and stretchability in its layers (more than of 100%). These strain gauges have a high compliance and can be used on the skin due to penetrating the thin layer of carbon nanotubes in a silicon rubber network. To do this, the conductive layer of carbon nanotubes are transferred on compliance, flexible, super stretchable polymeric layer called the EcoFlex using two methods of spraying and filtration. This polymer is a family of silicon rubber. In this study, the sensitivity of strain sensors is controlled by changing the concentration of nanomaterials in the sensor layer and changing the sensor geometry. Loading and unloading rates impress the sensitivity, too. It is shown that the relationship between sensitivity and width is direct and the relationships between sensitivity and length, concentration of nanomaterials as well as loading rate are reverse. At different levels of strain, piezoresistivity diagrams are highly linear and show the least deviation, however, all of the sensors have at least is 7% residual resistance. The piezoresistivity diagrams -show the efficiency of the sensor conductivity- can be obtained by measuring resistance variations of the fabricated sensors versus strain. Due to the need for high sensitivity and flexibility in a wearable sensor to show human physiological signals for personalized health-care, this study focuses on carbon nanotubes that can make a network. In addition, a wrinkle trick is used to increase stretchability. The sensors are characterized after the fabrication and the highest sensitivity of 4.6 is obtained in strains less than 10%. The maximum strain is 160% in cases that the piezoresistivity diagram is in linear state. Due to the ability to install directly on the skin or clothes, the fabricated sensors can be used as wearable strainers or pressure sensors to detect physiological and motional signals of humans or animals. Unlike existing sensors, the developed sensors are compatible with the human skin and do not hurt it, because of the closeness of their Young's modulus to the skin Yang’s modulus.
