When ceramic capacitors crack due to how fragile they are, this can cause problems because they are often located within implants such as heart pacers and also in spacecraft. When the cracks form, they can start to conduct electricity which can cause major damage.
A group called NIST has researched was to solve this by sending a very high pitched frequency the through the capacitor. This cause vibrations and they can use these vibrations to find cracks if there is a shift in the frequency. They can fix the problem before it cause any more harm.
