Micro-positioning platform plays an important role in the field of precision positioning such as microelectronics, robotics and biomedicine. This paper proposes an equal-stiffness and equal-stroke 2D micro-positioning platform, which is driven by piezoelectric actuators. The overall structure of the 2D micro-positioning platform adopts a nested structure and the displacement magnification mechanism adopts two hourglass displacement magnification mechanisms. The displacement magnification ratio of the hourglass displacement magnification mechanism was studied, and its structural parameters were optimized. Static stiffness analysis and simulation analysis of the micro-positioning platform were carried out. The simulation stiffness of the micro-positioning platform in the XY direction is 46873 N/m and 46832 N/m respectively. The experimental prototype of the micro-positioning platform was built. Through the measurement experiment with the prototype, the maximum stroke of the micro-positioning platform in the XY direction is 489 μm and 493 μm respectively; the maximum coupling ratio in the XY direction is 2.38% and 2.70% respectively. The research indicates that the micro-positioning platform had the characteristics of small size, equal long stroke, equal stiffness and low coupling ratio in the XY direction. Full article

Abstract: Thick film technology for the fabrication of high-quality piezoelectric and ferroelectric ceramic films is of increasing importance in the field of sensors, actuators, energy harvesters, and energy storage devices. The fabrication of these emerging functional devices, especially by conventional solid-state sintering method or many other thin or thick film processes is still challenging because the requirements of higher processing temperature and large residual stress. Therefore, a novel innovative processing technique is needed which meets the increased requirements of the ceramic thick film technology in terms of mass production, processing time and cost, integration capability in monolithic structures and miniaturization. A promising technology that meets all these requirements is the aerosol deposition (AD) technique. AD is a dry spray coating technique that uses the high kinetic energy of fluidized mixture of submicron size solid ceramic particles and carrier gas. AD method is based on the mechanism of shock-loading solidification in which submicron size ceramic particles with the velocity of subsonic speed typically are collided on the substrate to form thick, high density, binderless ceramic films at room temperature. This review focuses on the recent advances in the field of lead-based and lead-free piezoelectric and ferroelectric films synthesized by AD technique. This review also emphasize different aspects of AD techniques such as mechanisms and features of AD technique, materials and processes, electrical and piezoelectric properties of AD films followed by the potential of AD in different applications such as sensors, micro-electro-mechanical-systems (MEMS), micro-actuators, and energy harvesting.

Keywords: Aerosol deposition, piezoelectric, ferroelectric, thick films, MEMS, actuator, energy harvesters.
