A stress/strain measuring sensor for the continuous monitoring of stress/strain conditions, especially in screwed bolts, along with a corresponding measuring process is disclosed. An arrangement, and a corresponding method, are provided that are uncomplicated and easy to implement, and enable a continuous monitoring of stress/strain conditions. This is attained using a sensor ( 1 ) that comprises a first inductor ( 3 ) and at least one additional element ( 2 ), which comprises at least one pressure-dependent first impedance ( 5 ) or a second impedance ( 5 ') and a second inductor ( 3 '), wherein the second impedance ( 5 ') and/or the second inductor ( 3 ') are pressure-dependent, so that when the amount of pressure applied to the element ( 2 ) changes, the resonant frequency of an electromagnetic resonating circuit ( 3, 5; 3', 5 ') that is formed by impedance ( 5, 5 ') and inductor ( 3, 3 ') changes.
