This paper describes a new method of protein deposition using surface acoustic wave atomizer and electrostatic force, named as SAW-ED. This method mainly consists of two parts, one is to make fine micro droplets from charged solution of protein by using surface acoustic wave atomizer (SAW), and the other is to deposit them with any shape on the substrate by using electrostatic force and insulating mask. As the atomization of SAW uses high resonant frequency, we can generate fine droplets whose diameter is very small compared with regular ultrasonic devices. These micro droplets are dehydrated immediately, and it is possible to generate droplets even in high conductive solutions, so it is possible to decrease the particles that are not activated.
