This paper appraisals state-of-the-art dielectric elastomer actuators (DEAs) and their forthcoming standpoints as soft which have freshly been considered a crucial power generation module for robots. DEs behave yielding capacitors, expanding in area attenuation thickness when voltage is applied. The initiates with the explanation of working principle grippers. Here operation DEAs include both p...

The success of the rechargeable Li-S cell is limited in part by the dissolution of lithium-polysulfide in the electrolyte. Remarkably, it is found that removal of the conventional membrane separator in a Li-S cell improves sulfur utilization and cycling performance, whether the sulfur is initially contained in the cathode or electrolyte. An optimized cell design yields discharge capacities as h...

(PPN)2C 16S18 was obtained by the addition of PPN+C1_ to a methanolic extract of Na2C4Sv, de­ rived from the reaction of C6S80 2 and NaOMe. Centrosymmetric C 16Si84consists of thiophene units unsymmetrically fused to two 1,4-dithiin rings. Solutions of C 16S]84~ convert to C8S82~ with heating. When C4S* (x ~ 8) is reduced by Na/NH3 followed by extraction and crystallization, one ob­ tains the b...

The potential of cesium polysulfide-flux reactions for the synthesis of chalcogenogallates was investigated by using X-ray diffraction and Raman spectroscopy. An investigation of possible factors influencing the product formation revealed that only the polysulfide content x in the Cs2Sx melts has an influence on the crystalline reaction product. From sulfur-rich melts (x > 7), CsGaS3 is formed,...

This paper presents a new type of contractile polymer-based electromechanical linear actuator. The device belongs to the class of dielectric elastomer actuators, which are typically capable of undergoing large deformations induced by an applied electric field. It is based on a novel helical configuration, suitable for the generation of electrically driven axial contractions and radial expansion...
