The main focus of this thesis is the study of thin metal films in microelectromechanical/nanoelectromechanical systems (MEMS/NEMS), ranging from application to fundamental behaviour. The use of metallic structural components is desirable since they are electrically conductive, optically reflective...

As common human computer interfaces(HCIs), touchscreen panels (TSPs) have been ubiquitously adopted in our daily life especially in the consuming electronics, and numerous industrial applications. However, force information has been a missing part in conventional TSPs, drawing limitations in the...

Resonant microcantilevers are promising transducers for bacteria detection because of their high sensitivities. Surface stress and mass from adsorbates affect the resonant frequency. We developed a novel method for decoupling the frequency contributions of a change in mass and surface stress on a...
