Design and Experiments of a Single-Foot Linear Piezoelectric Actuator Operated in a Stepping Mode
IEEE transactions on industrial electronics (1982. Print), 2018A single-foot linear piezoelectric actuator is proposed in this paper, and a new exciting method for the stepping motion is discussed. The proposed actuator works in the hybrid modes of the second horizontal bending vibration and the second vertical ...

Micromanipulation requires very high resolution robotic systems in order to achieve repeatabilities and precisions that are compatible with the dimension of the objects being manipulated. This makes it preferable to use compliant structures rather than articuflated mechanisms, at least close to end-effectors.

Graphene‐Based Actuator with Integrated‐Sensing Function
Advanced Functional Materials, 2018Flexible actuators have important applications in artificial muscles, robotics, optical devices, and so on. However, most of the conventional actuators have only actuation function, lacking in real‐time sensing signal feedbacks.

Actuators are materials and devices that are able to change their shape in response to changes in environmental conditions and perform mechanical work on nano-, micro-, and macroscales. Among the huge variety of different actuators, polymer-based ones are highly attractive because of a number of properties such as sensitivity to a broad range of ...

An actuator surface can be defined as a two dimensional geometric region in a fluid at which a discontinuity in any flow property can occur [26]. We confine ourselves to a more restricted definition. We will use the term actuator surface for a two dimensional region in a fluid on which an external force field is concentrated. At this surface we have to

Actuator Performance Degradation of Piezo-Composite Actuator LIPCA under Cyclic Actuation
Key Engineering Materials, 2004This paper is concerned with the fatigue characteristics of LIPCA (LIghtweight Piezo-Composite Actuator) device system. LIPCA device system is composed of a piezoelectric ceramic layer and fiber reinforced light composite layers, typically a PZT ceramic layer is sandwiched by a top fiber layer with low CTE (coefficient of thermal expansion) and base ...
