An MRI system at small physical dimensions can be developed using a piezoelectric-microcantilever system with the capability of sensing magnetic fields in the range of microtesla to picotesla at room temperature conditions . The RF magnetic field induces voltage in the piezoelectric material which is amplified by the microcantilever which also filters out the signal around its resonant frequency. The cantilever vibration is measured using an optical detection system or by using capacitance to impedance converter. A thick block of piezoelectric material is used as a transmitter in order to replace the transmitting coil.
