A microgripper using piezoelectric actuation for micro-object manipulation
Design, fabrication and tests of a monolithic compliant-flexure-based microgripper were performed. The geometry design and the material tresses were considered through the finite element analysis. The simulation model was used to study in detail profiles of von Mises stresses nd deformation. The maximum stress in the microgripper is much smaller than the critical stress values for fatigue. The ...
متن کاملThe Actuation Response of Model SMA Hybrid Laminates
This paper presents the results from an experimental study on the actuation response of composite laminates containing Shape-Memory Alloy (SMA) actuators. Unidirectional glassfibre reinforced epoxide laminates were constructed containing Ni-Ti SMA actuators orientated parallel to the glass-fibre direction. The volume fraction of actuator was varied in the range 0 to 2.5 ~ 0 1 % . These laminate...
متن کاملDesign and Development of a Sun Tracking mechanism using the Direct SMA actuation
In recent years, the growing global interest in the conservation of environment has provided a fresh impetus for research in the area of solar energy utilization. Already, installation of solar energy extraction devices such as solar panels, solar water heaters, solar cookers etc. is becoming popular in urban buildings. Most of these devices consist of a solar receptor that is kept facing the s...
متن کاملInvestigation of Au/Si Eutectic Wafer Bonding for MEMS Accelerometers
Au/Si eutectic bonding is considered to BE a promising technology for creating 3D structures and hermetic packaging in micro-electro-mechanical system (MEMS) devices. However, it suffers from the problems of a non-uniform bonding interface and complex processes for the interconnection of metal wires. This paper presents a novel Au/Si eutectic wafer bonding structure and an implementation method...
متن کاملPractical Alignment Tools and Techniques
Accurate sawing requires attention to proper alignment and maintenance. Alignment is critical to modern sawmills using thin kerf saws. In fact, the improvements in machine design were critical to the development of thin kerf sawing systems. About two-thirds of sawing problems are caused by misalignment, not saw preparation. Good alignment reduces down-time and machinery wear and should be part ...
