Abstract. The main tasks and results of the research are as follows. The tensoelectric properties of undoped and iodine-doped silk fibers of the "L-28X" variety were determined under the influence of uniaxial pressure. The research was carried out in the temperature range of 300-360 K and voltage in the range of 0-100 V. According to the research results, as the pressure increased, it was observed that a higher current passed through silk fibers doped with iodine compared to the undoped sample. All samples prepared as objects of research were subjected to the current passing through Ohm's law. Compared to the undoped sample, it was found that the current passing through the doped sample is several times higher, and the electrical conductivity increases under the influence of uniaxial pressure. It was determined that the doping time depends on the conductivity and the change in the concentration of charge carriers. Entering molecules settle in the lattice defects of the polymer, form a deep layer in the forbidden band and provide conductivity.
