Abstract
Abstract Composite piezo-electric members having an intended structure are fabricated based on the LIGA process which includes the exposure of synchrotron radiation X-rays, development and lithography. With the intention of reducing the cost of the X-ray exposure mask, it is made of wire gauze having a regular pattern and formed by electrocasting.
