Printer head using shape memory alloy and method for manufacturing the same

摘要

Disclosed are a printer head using shape memory alloy and a method for manufacturing the same. The printer head using shape memory alloy comprises a substrate; space parts defined at both sides of the substrate; a vibrating plate formed on the substrate such that it covers the space parts, to be vibrated while being changed in its contour depending upon temperature variation, the vibrating plate including a shape memory alloy layer and a silicon dioxide layer; an electrode formed on the vibrating plate to have a desired pattern; an insulating layer formed to protect the electrode; an ink storing chamber formed between the space parts of the substrate for storing ink; a pressure chamber defined on the vibrating plate for containing ink, the pressure chamber discharging ink by vibration of the vibrating plate; a fluid passage plate formed at a side of the pressure chamber; a fluid passage formed by the fluid passage plate for allowing the ink stored in the ink storing chamber to flow into the pressure chamber; a nozzle plate attached onto the fluid passage plate for allowing ink to be fired in the form of droplets when the vibrating plate is vibrated; and a plurality of nozzles formed in the nozzle plate and firing ink to a recording device.
