A new method to detect protective glove penetration in conductive solution was developed to increase penetration detection sensitivity and accuracy. Penetration by non-conductive materials was detected by a penetration indicator, which is the ratio of the glove-conductance time derivatives to the glove-capacitance time derivatives. Penetration by conductive materials was detected by a penetration indicator, which is the product of glove conductance time derivative and the glove capacitance time derivative. The comparison tests showed that under the test conditions the signal-to-noise ratio (signal is referred to the maximum magnitude of a penetration indicator during penetration, and the noise is referred to that during membrane hydration and glove movement) of this method is higher than other existing methods in both non-conductive and conductive penetration detections.
