Electroactive Polymers for Robotic Application: Artificial Muscles and Sensors
Electroactive polymers (EAPs) reply to electric stimulation with huge deformations. they're dynamic actuators that have attracted realization from an interdisciplinary viewers of engineers and scientists. An permitting EAP expertise is rising which makes an attempt to mimic the houses of usual muscle and which, for that reason, can practice a distinct functionality in quite a few biologically-inspired robotics purposes.

Sponge-like structures are formed when the solvent diffuses out faster than the non-solvent diffuses in [4]. For the regeneration of cellulose from its solution, the exchange of solvent with non-solvent leads to a desolvation of the cellulose molecules and to the supposed reformation of the intra- and intermolecular hydrogen bonds [5]. While most types of regenerated cellulose have crystal form of cellulose II, having antiparallel chain packing, their mechanical and surface chemical properties are known to depend strongly on the type of cellulose solvent and coagulant, as well as the conditions of regeneration such as temperature and time.
