Реферат: Electroadhesion, adhesion induced by an electric field, occurs between non-sticky cationic and anionic hydrogels. When gel and tissue are placed under an electric field, the pair strongly adhere, and the adhesion persists indefinitely thereafter. Applying a direct current (DC) field with reversed polarity eliminates the adhesion. The use of electroadhesion can seal cuts or tears in tissues or model anionic gels. In an example, electroadhesion works with the aorta, cornea, lung, and cartilage. In another example, electroadhered gel-patches provide a robust seal over openings in bovine aorta, and a gel sleeve is able to rejoin pieces of a severed gel tube.
