Abstract: In an embodiment an electric circuitry includes at least a first delay chain of a plurality of delay elements and at least a second delay chain of a plurality of delay elements being arranged on a substrate, the respective delay elements of the at least one first and second delay chains are configured to provide a propagation delay time depending on strain applied to the substrate, wherein the delay elements of the at least one first delay chain have another orientation on the substrate than the delay elements of the at least one second delay chain, and a processing circuit configured to determine a magnitude of the strain applied on the substrate based on a first signal propagation delay time of the first delay chain and a second signal propagation delay time of the second delay chain.
