Abstract: According to an aspect there is provided a sensor circuit for use in a body and for communicating measurements of an in body property to a signal analyzer, the sensor circuit comprising a resonant circuit that is responsive to a first radio frequency, RF, field to receive a carrier signal, the resonant circuit having: a first transducer, wherein a first electrical property of the first transducer is dependent on the in-body property, and a second transducer, wherein a second electrical property of the second transducer is dependent on a second pulsed field; wherein the carrier signal received by the resonant circuit is modulated by changes in the first electrical property due to the in-body property and changes in the second electrical property due to pulses in the second pulsed field.
