Nanomechanical system is a nanometer scale moving element. The motion of nanomechanical structure introduces us several interesting features such as ultrasensitive sensor based on mass change, nonlinear behavior and quantum mechanical behavior. Researchers try to push the mechanical structure into its extreme to investigate its extreme behavior mainly quantum mechanical behavior. To study quantum mechanical property of mechanical structure, we have to have high quality mechanical structure and ultrasensitive motion detection technique. In this seminar, I will briefly cover the overall research trend about nanomechanical systems. Then I will focus on the current research efforts in KRISS related to parametric amplification for small signal detection and superconducting qubit coupled mechanics project for quantum measurement with mechanical structure.
