PROJECT TITLE :

Electroactive Shape-Fixing of Bucky-Gel Actuators

ABSTRACT:

Electromechanically active polymers (EAP) behave as actuators, i.e., quickly change their shape when subjected to electrical stimulus. However, in applications where a gentle state of an actuator is required for an extended amount of time (e.g., displaying characters of Braille text), EAPs want a lively driving signal. Form memory polymers, on the other hand, will be fastened to a most popular form using applicable stimuli like temperature change and mechanical stress. Combining the electromechanical properties with the form memory functionality could increase the efficiency and utility of EAP materials. As bucky-gel actuators–-a subtype of EAPs–-have been reported to possess a quite characteristic viscoelastic response, this paper proposes to implement them as form-fixable EAPs. We tend to use four completely different form-fixing techniques, out of that two enable programming the bucky-gel actuator during a controlled direction while not any external stress or temperature modification. These shape-fixing ways utilize composite driving signal consisting of high-frequency section to come up with Joule heating among the fabric whereas low-frequency rectangular component deforms the bucky-gel laminate. It's concluded that bucky-gel actuators can achieve steady deformation by using solely the electrical input. By using the proposed strategies for adding the shape-fixing functionality to an existing EAP device, no constructional changes of the system are required.
