Recently, electrically driven conducting polymer (CP) coated yarns have shown great promise to develop soft wearable applications because of their electrical and mechanical behaviour. However, designing a suitable yarn actuator for textile-based wearables with high strain is challenging. One reason the low voltage drop along yarn, which results in only part being active. To understand mechanism...

We demonstrate that a flexible dielectric-barrier-discharge (DBD) plasma actuator fabricated by an inkjet printing process using metallic inks generates stable surface discharge and ionic wind for active airflow control. The establishment of practical fabrication method DBD actuators is critical issue to be tackled industrial applications. requires just the sintering processes while conventiona...

We proposed the use of a Toda-Rayleigh ring as a central pattern generator (CPG) for controlling hexapodal robots. We show that the ring composed of six Toda-Rayleigh units coupled to the limb actuators reproduces the most common hexapodal gaits. We provide an electrical circuit implementation of the CPG and test our theoretical results obtaining fixed gaits. Then we propose a method of incorpo...

AC machines are applied in actuator systems for many applications. The development of fast processors open up the possibilities to apply new techniques for identification and control of electrical drives in real-time, so as to improve and optimize their performances. The paper presents a systematic approach to identify the physically relevant parameters of an ac machine. Special attention is pa...

in this paper the design of a biped robot actuated with shape memory alloy (sma) springs with minimum degrees of freedom is presented. sma springs are a class of smart materials that are known for their high power to mass and volume ratios. it was shown that utilizing spring type of smas have many advantages as large deformation, smooth motion, silent and clean movement compared to ordinary typ...

Electromagnetic transducers have been used extensively for active feedback control of mechanical vibration. In this paper, we demonstrate a new technique where an electrical impedance, connected to the terminals of an electromagnetic actuator, is designed to reduce vibration in the host structure. By measuring the coil terminal voltage and controlling the resultant current or vice-versa the cou...

The design and application of a patented active actuator design that combines the radial and axial actuator into one combination radial-axial actuator is presented. The theory of operation of the actuator is defined and magnetic finite element analysis modeling shown verifying operation. Its mechanical construction is then presented to show how this actuator configuration is successfully integr...

In this study, free vibration of a foam-core orthotropic smart composite cylindrical shell (SCCS) filled with a non-viscous compressible fluid, subjected to combined electro-thermo-mechanical loads is investigated.  Piezoelectric polymeric cylindrical shell, is made from polyvinylidene fluoride (PVDF) and reinforced by armchair double walled boron nitride nanotubes (DWBNNTs). Characteristics of...
