Abstract
Hydrogel is a water swollen “soft material” made of synthetic polymers. We found that the hydrogels can contract and dilate reversibly under electric stimulus (Electro-Activated Mechanochemical System). On the base of this principle a variety of biomedical divices such as artificial muscle lifting up and down the load repeatedly, permselective chemical valve membrane opening and closing the pores, controlled drug delivery systems (missile drug model) and others were developed.
