Determination of relative and absolute humidity is essential for industrious, in-home, healthcare and a number of other applications. Although there is a large variety of a different type of commercial sensors, some specific applications might require solutions that flexible, cover large-areas, relatively low-cost and simple in production. Smart textiles and sensing properties may provide solutions for areas facing challenging requirements, whether bring improvement to some aspects in construction, operation, physical or other properties.The current report presents a preliminary study on the concept of a textile humidity sensor, design and development issues cohered with further application particularities. Several designs of the sensor have been implemented by conventional embroidery on a textile substrate using conductive yarns. In order to achieve efficient operation of the sensor with available materials and technologies, investigations on the choice of the appropriate design of the prototype including the specific pattern for the capacitor embroidery, yarns and substrate materials, have been performed and solutions for improving the initial prototype of the sensor are suggested.
