Smart textile materials have huge applications on wearable physiological monitoring devices. Monitoring of muscular stretch and bending is important for sports and geriatric people due to their continuous physical activities and due to age factors their muscles become weak which leads to muscular disorders. In this research, a carbon nanotube (CNT) based smart fabric is developed for monitoring the bending activities of the hand with respect to wrist moment in different angles of bending. The conductive fabric is developed from cotton fabric, coated with multi-walled carbon nanotube (MWCNT) synthesis using a hydrothermal process. The developed material acts as a sensor which is placed along with the glove near the wrist. The sensor resistance is tested in four different zones. The sensor converts the bending angle stimuli into voltage, such that the various zones within the range of motion of the wrist are comprehended by the algorithm. The range of resistance was monitored with the aid of a serial monitor. The results show resistance values exceeding 190  \(\Omega \) for the Green Zone; a range of 182–190  \(\Omega \) for the Yellow Zone; 174–182  \(\Omega \) for the Red Zone; and resistance values dipping below 174  \(\Omega \) for extension beyond 51o, where 1000  \(\Omega \) was used as the known resistance of the circuit.
