An SAW resonator transducer is provided comprising a substrate on which interdigitated electrodes are deposited, the electrodes having a signal input and a signal output, the transducer being adapted for coupling at a given orientation on a member whose strain is to be measured. A driving signal is applied to the signal input of the transducer and an output resonant frequency is detected at the signal output of the transducer when it is driven by the driving signal. The output signal is processed to derive information as to the strain generated in the transducer induced by stress in the substrate due to stress applied to the substrate by way of a member to which the transducer is coupled.
