摘要： The present disclosure is directed to an intracranial pressure gauge which comprises a powerless resonance circuit composed of a coil and a condenser; a sensor equipped with a pressure-sensitive section capable, when implanted under the scalp, of changing either the inductance of the said coil or the capacitance of the said condenser in response to a change in intracranial pressure; and a grid dip meter capable of externally measuring the change in the resonance frequency of said sensor.
