Composite material, has ferroelectric tubes arranged parallel and one upon other with specific distance under utilization of maximum packing density, such that direct connection between inner and outer surfaces of tubes does not exist

摘要

The material has ferroelectric tubes having electrodes and embedded in a non-ferroelectric matrix material. The tubes are arranged parallel and one upon other with a distance of less than 500 micrometer under utilization of maximum packing density, such that direct electrical connection between the inner and outer surfaces of the tubes does not exist. The aspect ratio of the tubes from length to diameter is less than 10 to 1 ratio.
