Resistive flex sensors can be used to measure bending or flexing with relatively little effort and a low budget. Their lightness, compactness, robustness, measurement effectiveness and power consumption make these sensors useful for manifold applications in diverse fields. , we provide a comprehensive survey of resistive flex sensors, taking into account their principles, manufacturing aspects, electrical characteristics and equivalent models, front-end conditioning circuitry, and physic-bio-chemical aspects. Particular effort is to reporting on and analyzing several applications of resistive flex sensors, related to the of body position and motion, and to the implementation of artificial devices. In to the human body, we consider the utilization of resistive flex sensors for the of physical activity and for the development of interaction/interface devices driven human gestures. Concerning artificial devices, we deal with applications related to the field, robots, orthosis and prosthesis, musical instruments and measuring tools. The literature is collected from different sources, including bibliographic databases, press releases, patents, master’s theses and PhD theses.
