A novel electrode structure consisting of a variable spacing interdigital electrode (VS-IDE) was proposed. The VS-IDE structure sensor was optimized to confine the electric field line within the sheds under test. The optimal sensor exhibited high amplitude, high sensitivity, and excellent stability. The capacitive proximity sensors can be used for quantitative evaluation of the aging of silicone rubber sheds.
