A micrometer scale method based on the principle of liquid rope coiling with the assistance of nonsolvent-induced phase inversion is introduced to fabricate YSZ coils. The YSZ coils with the filament diameter of several hundreds of micrometer exhibit stable spring properties and excellent elongation at failure. With the spring rate in the range from similar to 2 N/mm to similar to 21 N/mm and the elongation up to 4.36%, both the two properties can be effectively controlled and tailored since they both strongly depend on the geometric dimensions varied with the process parameters. Besides, the simple method provides an alternative method for the large-scale production and customization of ceramic coils with diverse applications.
