An effort made towards the performance improvement for an XY micromanipulator featuring parallel architecture and flexure hinges has been presented in this paper. Through the implementation of four steps evolution of the original structure, a new manipulator with decoupled motion is finally obtained, which owns an enlarged workspace and eliminated stiffening and buckling phenomena. The merits o...

INSTRUCTIONS Precision nano-positioning techniques have become very important for biomedical science, optics and microscopy. PZT and flexure compliant mechanisms are widely used in these various fields and applications within these fields. Compliant mechanisms are flexible structures, which can generate the desired motions by undergoing elastic deformation instead of through rigid linkage/joint...

Needle-based procedures, such as biopsy, thermal ablation, brachytherapy, and drug delivery, provide a minimally invasive means for diagnosis or treatment. The success of the procedure relies on the needle reaching the physician’s desired target (typically identified on a medical image) accurately. However, due to tissue deformation and the accuracy limits of human hand–eye coordination, the ne...

Recent interest in high-speed scanning probe microscopy for high-throughput applications including video-rate atomic force microscopy and probe-based nanofabrication has sparked attention on the development of high-bandwidth flexure-guided nanopositioning systems (nanopositioners). Such nanopositioners are designed to move samples with sub-nanometer resolution with positioning bandwidth in the ...

Once these features are analytically and experimentally verified, they can lead to significant advantages in terms of range of motion, accuracy of motion and simplicity in motion control. Most parallel kinematics flexures have a limited range of motion since larger motions induce non-linearity and parasitic coupling, which in turn limits accuracy. Despite being parallel mechanisms, the proposed...

introduction: angle and internal position of lateral pterygoid muscle leads to contraction over two half of the mandible in maximum opening and protrusion position so it can affects impression prosthetic procedures. the aim of this study was to evaluate the mandibular flexure in two transverse and antro-posterior dimensions. methods: seventy edentulous patients at mashhad faculty of dentistry a...

Journal: :Actuators 2022

Ongoing interests in high-speed precision actuation continuously sparks great attention on developing fast amplified piezoelectric actuators (APAs) with compliant mechanisms. A new type of APA enhanced resonance frequency is herein reported based a hybrid amplifying mechanism. two-stage displacement flexure amplifier proposed by synthesizing the lever-type and semi bridge-type mechanisms compac...
