Abstract

A toothed belt includes at least one tension member and a plastics material matrix which at least partially encases the tension member. The at least one tension member extends in the plastics material matrix in a running direction and teeth of the toothed belt are formed transversely to the running direction in the plastics material matrix. The tension member is formed from an electrically conductive material and the plastics material matrix is formed from an electrically insulating material. The toothed belt has at least one electronic component which is embedded in the plastics material matrix and has at least one sensor which detects data on a condition parameter of the toothed belt. The at least one electronic component is coupled to the tension member via at least two voltage taps to tap a voltage induced in the tension member to supply the at least one electronic component with power.
