The final thesis presents the development of a measuring cell for wireless shaft torque measurement. The theory of torsion formation in a round cross-section shaft is presented and the way in which we can convert the deformation of a material into an electrical signal. Then we send it wirelessly and convert it into a form from which we can extract the necessary information. For this purpose, a system was designed and divided into a measuring and receiving part. Both parts are connected by nRF24L0+ modules which take care of wireless data transmission. We performed the cell function test, evaluated the results and made suggestions for improvement.
