Mechanics deals with the motion and deformation of bodies under the action of forces. In this talk several special topics of mechanics in micro- and nano-systems will be addressed:
Ultrasonic forces can be used to manipulate particles in fluids in a controlled way. By using spatially periodic fields generated by a vibrating plate, many clusters of particles can be dealt with in parallel. As an example manipulation of biological cells will be demonstrated.
Wave propagation in solids can be applied to small systems if the wavelength is much smaller than the dimensions of such systems. An optical pump probe setup can be used to both excite and detect mechanical waves in the GHz range to probe thin films, build filters and investigate waves in AFM tips.
Mechanical properties of microsystems need to be tested on small systems because materials are typically different from macroscopic materials. Specially designed experiments are presented including results on “size effects” in copper foils.
