An apparatus for determining a force Fapplied to a tip of an electrical impedance spectroscopy probe includes a load cell, accelerometer, and a processing means. The probe tip has a substantially planar distal end for contacting human or animal tissue. The load cell measures the force Fapplied axially along a longitudinal axis when the probe tip is in contact with human or animal tissue. The accelerometer measures a gravity vector A. The apparatus includes a means for compensating for the mass of the probe tip using the measured force and the gravity vector to produce a calibrated measurement force F applied to the probe tip.

Apparatus and methods for determining force applied to the tip of a probe

Apparatus for determining the electrical conductivity of target cervical tissue using magnetic impedance spectroscopy comprising: an excitation coil for producing a magnetic field which is capable of inducing currents in the target cervical tissue; a gradiometer for detecting perturbations in said magnetic field caused by said induced currents, the gradiometer including screening means for minimising sensitivity to tissues other than the target tissue; processing means for determining an electrical conductivity of said target cervical tissue from said perturbations.
