Efficient and reliable external mechanical actuation is one of the key factors for a successful magnetic resonance elastography (MRE). Existing actuators just attaches to the surface of human tissues and only unidirectional force is applied. A new adsorption actuator is proposed in this study to cope with this problem. It adsorbs soft tissue by creating a vacuum environment between the actuator and...
The Transfer Equipment Cask (TECA) is a key solution for Remote Handling (RH), and the bidirectional sealing door system (BSD) is the key component of the TECA. The control system of BSD is introduced in this paper. Moreover, the experiment on TECA indicates that the design of control system is feasible and the effect is satisfactory.
Movement in micro-scale precision cannot be achieved by unaided human hand. This paper describes the design of a six degrees of freedom (DOF) micromanipulator based on compliant parallel mechanism. It is capable of delivering 6-DOF pure motions with high precision and featured by piezo-driven actuators, flexure hinges and integrated force sensor that can provide the system with real-time force information...
This paper presents the development of a micro-scale positioning device based on two degrees of freedom (DOF) plane compliant parallel mechanism, which is featured by piezo-driven actuators and flexure joints, integrated force/torque sensor that capable of delivering 2-DOF motions with high precision and providing real-time force/torque or position information for feedback control. With optimization...
