A design concept for multilayer piezoelectric microactuator using piezoelectric coefficient d31 was particularly stressed.
The observations have promoted an understanding of the magnetic domain structure in ferromagnetic shape memory alloy films, and also provided essential information for developments of magnetic field-driven microactuators using these films.
The fundamental MEMS polysilicon electrothermal microactuator uses resistive (Joule) heating to generate thermal expansion and movement.
The microactuator uses high-aspect ratio etching and deep trench isolation to generate high force densities and good mechanical robustness.
This analytical modelling of the melting process can provide useful information for designing optimal electrothermal hydraulic microactuators using phase change materials (PCMs) and their operating actuation characteristics.
For microactuators using friction bearings there is a great need for a general understanding of friction and wear phenomena.
