Langmuir, 2014
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 ...

Effective Actuation: High Bandwidth Actuators and Actuator Scaling Laws
2001Abstract : The project advances active flow control to enable new Air Force capabilities. Advances in both the development of new actuator hardware and in understanding the flow physics have been achieved. Four key new advances have been achieved in Phase I of this AFOSR/STTR Program. First, a new high power (125-160 dB), high bandwidth (factor of 8.6),

Smart Actuators for Colonoscope Actuation
The International Conference on Electrical Engineering, 2014In recent years, much has been studied on the colonoscope because it is a very important tool for diagnosing colon cancer, which is the second leading cause of cancer in the developed countries. Colonoscopy is one of the most technically demanding endoscopic examinations in the modern health service.

Adaptive Finite Time Control of Nonlinear Systems Under Time-Varying Actuator Failures
IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2019This paper proposes a new finite-time tracking control strategy for a nonlinear uncertain system with actuation failures. The presented control scheme is not dependent on the exact model of system and actuation failures.

A Novel Stick–Slip Piezoelectric Actuator Based on a Triangular Compliant Driving Mechanism
IEEE transactions on industrial electronics (1982. Print), 2019There is a growing demand for positioning actuators with a higher resolution, accuracy, speed, and driving force. Various piezoelectric actuators have been proposed to meet these requirements; however, they all have inherent limitations.
