Nanoindentation technique is commonly used to characterize the mechanical properties of thin films. However, the validity of the measurements is greatly affected by the indentation depth and the substrate properties. The purpose of this study is to understand the influence of the substrate properties, the thin film thickness and the mechanical properties of the thin film itself on force-displacement...
The nanoindentation experiment is an established technique for the determination of hardness and Young's modulus of thin films. This standard data set is not sufficient to be used as input to finite element simulations , because elastic-plastic material data is being required for analysis of reliability of metal layers. Therefore stress-strain curves are being determined by fitting the force displacement...
Stretchable electronics offer potential application areas in biological implants interacting with human tissue. Furthermore, they facilitate increased design freedom of electronic products. Typical applications can be found in healthcare, wellness and functional clothes. A key requirement on these products is the ability to withstand large deformations during usage without losing their integrity (i...
This paper is to perform a design optimization of micromachined piezoelectric transducer by maximizing the system exciting sensitivity. The transducer is a membrane-based micromachined transducer with the piezoelectric film to excite the membrane vibrating. In this study, the exciting sensitivity is taken as the optimization objective. Specifically, when fixing the exciting signal, the transducer...
