In this paper, a new three translational degrees of freedom (DOF) compliant parallel micromanipulator (CPM) is proposed, which has an excellent accuracy of parallel mechanisms with flexure hinges. The system is established by a proper selection of hardware and analyzed via the derived pseudo-rigid-body model. In view of the physical constraints imposed by both the piezoelectric actuators and fl...

The measurement of the acoustic properties of highly attenuative materials such as bitumen is very difficult. One possibility is to use measurements of the extent to which filling a cylindrical waveguide with the material affects the dispersion relationship of the cylinder. Torsional modes have been excited using piezoelectric transducers placed at one end of the cylinder, while the phase veloc...

the output of a piezoelectric nanogenerator based on zno nanowire is largely affected by the shape of nanowire. in order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance. this paper presents the various behavior of ...

This technical note numerically and experimentally studies a vibration energy harvester (VEH) consisting of set two parallel elastic steel sheets (ESSs) piezoelectric patches (PZTs) in pipe flow. The roots the are fixed on base with PZTs to form double inverted flag harvesting system (DIF-VEHS). In this note, semi-circular receiving device (receiver) was added free end steel, cylinder installed...

One of the major disadvantages of the minimally invasive surgery (MIS) is the lack of tactile feedback to the surgeon. In order to identify and avoid any damage to the grasped complex tissue by endoscopic graspers, it is important to measure the local softness of tissue during MIS. One way to display the measured softness to the surgeon is a graphical method. In this paper, a new tactile sensor...

Piezoelectric nanogenerators (PNGs) are capable of converting energy from various mechanical sources into electric energy and have many attractive features such as continuous operation, replenishment and low cost. However, many researchers still have studied novel material synthesis and interfacial controls to improve the power production from PNGs. In this study, we report the energy conversio...

A novel method of improving the precision pressure sensor has been proposed by applying design and correction technology that measures explosion in cylinder combustion chamber low-speed 2-stroke diesel engine for ships. To enable dynamic measurement high-temperature high-pressure environments, a diaphragm-type piezoelectric designed using quartz. The fast median filter algorithm adopted modifie...
