Abstract:
The primary objective of this experiment was to determine if electrical potentials could be detected in bone as a result of an application of stress. The value of the stress-generated potential was found to be 3.6 + 0.5 mV upon loading of a 5 kg weight, and 2.0 + 0.5 mV upon loading of a 2 kg weight. The magnitude of the SGP was also found to vary with strain rate and stiffness. Increasing the strain rate yielded a value of 6 mV for the SGP (when using the 5 kg weight), while decreasing the strain rate yielded a value of 1 mV for the SGP (also with the 5 kg weight). When stress was applied with the 5 kg weight to a chicken bone of lesser stiffness, the magnitude of the SGP was found to increase to 7.4 mV.
