Drive component of a micro-needle system and method for driving the same, micro-needle system and method for fabricating the same

A micro-needle system, comprising a micro-needle component and a drive component fit tightly with each other;

• wherein the micro-needle component comprises a plurality of micro-needle protrusions, each of which comprises a micro-needle through-hole;
• the drive component comprises a substrate with a groove;
• a bottom electrode in the groove;
• an electro-active polymer layer, covering the bottom electrode, in the groove;
• and an upper flexible electrode covering the electro-active polymer layer;
• wherein the upper flexible electrode and the bottom electrode are configured to generate a voltage, and the electro-active polymer layer is configured to generate a strain under the voltage;
• and
• a liquid storage region is arranged between respective micro-needle through-holes of the micro-needle component and the groove of the drive component, and the liquid storage region is at a side, facing away from the bottom electrode, of the upper flexible electrode.
