A new piezoceramic material manufactured using nanotechnology improves ignition-system performance. The "nano-fiber-in-nano-pore" technology uses metallic nano-fibers to increase voltage output, power-output efficiency, and effective surface area of piezoelectric ceramics.

| A piezo high-voltage power supply offers efficiency as high as 85-90%. |
In ignition systems, the materials' enhanced electrical characteristics allow engineers to use the material three ways to improve ignition performance:
-
As a high-voltage transformer charging a high-voltage capacitor to deliver a single spark
-
As a high-voltage igniter delivering a series of high-voltage sparks in a frequency range from 0.1 Hz to 100 kHz
-
As a high-voltage discharger producing a stable and continuous discharge across a gap.
