Sensors for in situ monitoring of elastic properties
Preliminary experiments have been carried out to examine an invention for in situ monitoring of elasticity. The elasticity monitor consists of a piezoelectric material placed in contact with an elastomer to form an oscillating system. Monitoring the resonant frequency, amplitude, or ''Q'' value of this system provides a measure of elasticity of the elastomer. The experiments are described and their results and implications discussed. 7 refs., 7 figs.
