Films of conducting polymers can be oxidized and reduced in a reversible way. Any intermediate oxidation state determines an electrochemical equilibrium. Chemical or physical variables acting on the film may modify the equilibrium potential, so that the film acts as a sensor of the variable. The working potential of polypyrrole/DBSA (Dodecylbenzenesulfonic acid) films, oxidized or reduced under...

This paper addresses the problem of motion planning for free-flying robots. Full state actuation is considered to allow for large displacements of the spacecraft. Motion planning is formulated as an optimization problem and kinematic as well as dynamic constraints are considered. The chosen optimization criteria are spacecraft actuation and final time. The proposed method allows solutions which...

Small hobby servo motors designed for remote controlled (RC) model cars and airplanes are commonly used actuators by robotic hobbyists. They also serve as actuation for a number of commercially available robotic kits. These inexpensive RC servo motors can serve as a useful low-cost alternative actuation method for student projects and laboratory investigations. This paper discusses two laborato...

Salmeterol + Fluticasone propionate (Seretide) 25/125mcg Metered Dose Inhaler: Each single actuation provides salmeterol xinafoate equivalent to 25mcg of salmeterol and 125mcg ...

The ability to manipulate the movement of surface microstructures is essential for the development of dynamic, responsive materials. We demonstrate that in addition to bulk actuation upon drying, a unique type of highly localized, directional actuation can be achieved when microstructures embedded in pH responsive gel are exposed to pH gradients. Theory and modelling elucidates the underlying m...

This paper presents a detailed AMT model composed of various components from multi-domains like mechanical systems (clutch, gear pair, synchronizer, etc.), pneumatic actuator systems (clutch actuation system, gear select actuation system, gear shift actuation system, etc.). The model is implemented using the Modelica modeling language in an objectoriented environment. The Modeling and simulatio...

Actuation functionality in a sensor network enables an unprecedented interaction with the physical environment. When used by a malicious distributed network however, actuation may become a potent new attack. In this work we explore a new general class of actuation attacks which aim to disable the sensing fidelity and dependability of a wireless sensor network. We propose a countermeasure to thi...

Low-power wireless actuation is attracting interest in many domains, yet it is significantly less investigated than its sensing counterpart, especially in large-scale scenarios. As a consequence, guidelines about which protocol, among the few existing ones, is best suited to a given scenario are generally lacking. In this paper, we investigate the relative performance of simple disseminationbas...

Nastic structures are potentially high-energy density smart materials that will be capable of achieving controllable deformation and shape change due to internal microactuation that functions on principles found in the biological process of nastic motion. In plants, nastic motion is accomplished through osmotic pressure changes causing a respective increase or decrease in cell volume, thereby c...

While there have been numerous reports on the electromechanical actuation of carbon nanotubes (CNTs), devices based on the photomechanical actuation of CNTs have been elusive until now. In this paper, we report the integration of single-wall carbon nanotube ensembles into micro-mechanical systems to realize a new carbon nanotube micro-opto-mechanical system (CNT-MOMS). CNT-MOM grippers were fab...
