The technique used to control the airflow is based on the electro-hydrodynamic actuator which is also called plasma actuator. This actuator ensures the airflow control thanks to the electric wind created by the electrical corona discharge. This ionic wind is developed at the profile surface tangential to the initial free airflow so that it has a significant effect on the boundary layer flow. Th...

Mechanical counter-pressure (MCP) space suits, which apply pressure to the wearer using tight-fitting materials rather than pressurized gas, offer numerous mobility and mass advantages over traditional gas-pressurized suits [1]. However, MCP design challenges related to pressure uniformity, pressure magnitude, and donning/doffing remain unsolved [2]. Previous MCP efforts have focused on passive...

Shape Memory Alloy (SMA) actuators are an effective way to reduce weight and to minimize the complexity of various systems including biomedical and more specifically. Prosthesis systems. As actuators, these materials have been used in a wide range of applications from thin film actuators to helicopter rotor actuators [1]. SMA actuators provide an interesting alternative to conventional actuatio...

One important challenge of microsystems design is the implementation of miniaturized actuation principles efficient at the micro-scale. Shape Memory Alloys have early on been considered as a potential solution to this problem as these materials offer attractive properties like a high-power to weight ratio, large deformation and the capability to be processed at the microscale. This paper review...

This paper presents the design and fabrication of a prototype model novel solar tracker that exploits unique properties shape memory alloy for its actuator. As against conventional trackers, proposed does not use motor changing position PV cell. The is in form spring used actuating. SMA moves panel to track Sun during day time back original at end day. structure only increases efficiency but al...

In this paper, we propose an original formalism inspired by Markov Decision Process in order to represent homogeneously actions and direct interactions between agents. Thanks to the introduction of individual rewards characterising the problem to be solved, this formalism is a first step towards the automatic computation of policies and use of available interactions. A simple problem of distrib...

The aim of this research is to introduce a semi-analytical approach for the analysis free and forced nonlinear vibrations bending shape memory alloy (SMA) beam; while, considering effect its pseudo-elastic behavior. In order create primary deflection, an appropriate pre-strain applied SMA beam using compression spring. A new material model was utilized simulate hysteric behavior beam, while dif...

Abstract Soft composite actuators can be fabricated by embedding shape memory alloy (SMA) wires into soft polymer matrices. Shape retention and recovery of these are typically achieved incorporating segments the actuator structure. However, this requires complex manufacturing processes. This work uses multimaterial 3D printing to fabricate with variable stiffness capable recovery. The hinges be...
