The invention relates to a circuit module, particularly a tire sensor module, at least comprising: a substrate (2a, 2b), on, or in which at least one component (6, 11, 12, 13) is attached, a piezo element (3), having at least one clamping region (3a, 3b) and at least one oscillating region (3b, 3a), wherein the piezo element (3) is clamped in its clamping region (3a, 3b) at the substrate, or at means attached to the substrate, and its oscillating region (3b, 3a) is received in an oscillating manner, contact points (10) provided at the piezo element (3) for reducing a piezo voltage, and a power supply circuit (12, 13), which receives the piezo voltage generated by the piezo element (3), and which serves as a voltage source for the power supply of the circuit module (1). Preferably, the piezo element (3) is clamped between two substrate elements (2a, 2b), which form at least one cavity (5), in which the at least one oscillating region (3b, 3a) of the piezo element (3) is displaceably received, and is limited in its oscillation. |
