ELECTROMECHANICAL SYSTEMS BASED ON POLYMER HYDROGELS FOR MICRO-SCALE ACTUATORS

The paper proposes a novel approach to the construction of actuators for automation and robotics based on the use of new electroactive polymer materials – swelling hydrogels. The hydrogel pH-sensitive materials containing two polymer components, crosslinked polyacrylic acid and polyvinyl alcohol, ar...

Subjects:
crosslinked polyacrylic acid and polyvinyl alcohol
are obtained. A procedure for the synthesis of hybrid hydrogel is described
and the achieved values of their characteristics
degrees of swelling in water and water solution of salt
are given. A method of hydrogel elements preparation with a specified geometric configuration was developed
and cylindrical and also ring-shaped samples were prepared. Mechanical properties of the prepared hydrogels at compression were measured. It is shown that the hybrid hydrogels exhibit higher strength and elasticity than the one-component polyacrylic acid hydrogels obtained by the same method. An actuator design is proposed with a hydrogel as a controlled element. An experimental layout of such actuator was constructed. The stability of material characteristics was determined
