Abstract

Abstract. During recent years, many investigations have been carried out to determine how to select
di erent materials for the making of Micro Electro Mechanical Systems (MEMS) and bio-MEMS. The
NiTi shape memory alloy thin lm has been much regarded as a promising candidate for MEMS due to
its unique shape memory e ect and high energy output. In this research, NiTi thin lm was fabricated
using a sputtering technique from separate elemental Ni and Ti targets. The characterizations of the
deposited lms were investigated using di erent analysis techniques, such as Field Emission SEM, DSC,
XRD, electrical resistivity measurement and nanoindentation.
