Soft-Actuator Myomer

Soft-actuator myomers are artificial muscles made from electro-active polymers (EAPs), designed to mimic the elasticity and strength of human tissue.

Soft-actuator myomers address the need for lightweight, flexible, and biocompatible actuators that can perform tasks requiring human-like dexterity and strength without the bulkiness of traditional rigid mechanical components.

These materials contain EAPs, which contract in response to an electric field. By applying a voltage, they can generate force and movement similar to biological muscle contractions.

• Conductive inks

Manufacturing involves synthesizing EAPs with specific properties, patterning them into desired actuator shapes, and integrating electrical contacts. This process requires precise control over polymer composition and structure.

The build process includes polymer synthesis, film casting or printing, electrode deposition, and device assembly. Each step must be carefully controlled to ensure the EAPs respond predictably to applied voltages.

Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking processes.
