Abstract Sensitive and stable perovskite X-ray detectors are attractive in low-dosage medical examinations. The high sensitivity, tunable chemical compositions, electronic dimensions, low-cost raw materials make perovskites promising next-generation semiconductors. However, their ionic nature brings serious concerns about water stability, limiting applications well-established technologies like crystal polishing, micro-processing, photolithography, etc. Herein we report a one-dimensional...
A piezoelectric-driven actuator based on coupling motion has been proposed and tested to achieve a large linear working stroke with high resolution. "Z-shaped" flexure hinges are exploited for the symmetric hinge mechanism reduce structural stress. Coupling is obtained by placing this an angle of θ = 20° slider. Experimental results indicate that effectively motion; maximum speed V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</sub> 6057...
Piezo-driven precision positioning platforms with large stroke are greatly demanded in both scientific research and industrial applications. Although various principles have been proposed to design piezo-driven platforms, the problem of backward motion commonly exists, hindering their To suppress motion, this paper, an idea by generating a forward frictional force balance reversed was proposed. Correspondingly, specific arc-shape flexure hinge designed generate via its elastic recovery....
With simple structure and control, impact inertial piezoelectric actuators are one promising type for precision positioning with large working stroke high resolution. However, their applications still face some challenges, especially the incompatibility between speed resolution as well motion instability due to overturning moment. Therefore, innovative design of is urgently required. In this article, by designing an asymmetric compliant mechanism a thick end thin generate friction driving...
Abstract Cell‐laden hydrogel fibers/tubules are one of the fundamentals tissue engineering. They have been proven as a promising method for constructing biomimetic tissues, such muscle fibers, nerve conduits, tendon and vessels, etc. However, current fiber/tubule production methods limitations in ordered cell arrangements, thus impeding configurations. Acoustic patterning is manipulation that has good biocompatibility, wide tunability, contact‐free. there few studies on acoustic fiber...
Aiming to simulate the experimentally observed three kinds of one-stepping characteristics in stick-slip piezoelectric actuators, i.e., backward motion, smooth and sudden jump, a new dynamic model is proposed with consideration deformation overall system. Being different from existing models that consider system as rigid body, stiffness coefficient damping are introduced newly model. By adjusting parameters according experimental conditions, these successfully simulated for first time this...
Micro/nano scratch testing is an effective technique for characterizing the mechanical properties and wear resistance of materials. In practical applications, most materials in equipment serve a vibration environment. However, scratching characteristics under environment have not been well investigated due to lack suitable instruments. To address this issue, article, we develop vibration-assisted micro/nano tester. Its working principle introduced, followed by designing analyzing platform....
To understand the relationship between damage mechanism of sapphire and anisotropic characteristic its crystal structure, in-situ scratch tests under confocal laser scanning microscope (CLSM) were performed along different directions C-plane wafer. The relation images normal/lateral forces was established. Craters in front contact region (CR) indenter material, subsurface special cracks separated from CR observed. As direction changed, these craters initiated propagated on left front, right...
