In addition, Interdigital Transducer (IDT) parameters also changed to be created the products with a smaller size and easy to handle where it also reduces the cost of this product.

The design of Interdigital Transducer (IDT) parameter is changes in several sizes and values for which it is able to provide greater efficiency in sensing sensitivity by using process simulation with CST STUDIO Suite software. Surface Acoustic Wave (SAW) device with the combination of pair electrode know as Interdigital Transducer (IDT) was fabricated on a piezoelectric substrate. However, within the technological advances, demand for device with low cost, high efficiency and friendly-user preferred. Due to increased demand in the international market for biosensor product, the product must be emphasized in terms of quality. This paper focuses on the enhancement and improvement of the Surface Acoustic Wave (SAW) device performance.
