Artificial Muscle Actuator
- OVER VIEW -
We have developed new actuators made of dielectric polymer which has overall good performances such as actuating pressure, strain, high, efficiency, fast response, high energy density, and adjustable complience like human beings one with low cost.
Miniature quadruped walking robot
This is a small legged robot using an artificial muscle actuator based on dielectric elastomer actuator. The robot is driven by a novel linear actuator called Multi-stacked Dilectric Elastomer Actuator, which can be easily embedded in the mechanism and ensures a compact design of the overall system.
Twisted Dielectirc Elastomer Stack Actuator
The purpose of this research is to make an actuator which is easily adaptable to use as artificial muscle by improving structure of stack-type Dielectric Elastomer Actuator (DEA). In contrast with previous stack-type actuator, Single body Dielectric Elastomer stack Actuators (SDEAs) is connected as single body without external frame so that it can be actuated in twisted and bended state like human muscle. Consequently, it is applicable with no design limitations of rigid frame and has the advantages of flexibility and weight lightening. Using the advantages of SDEAs, we fabricate 2-ply structure SDEAs which can amplify the contraction rate and compare the performance with the non-ply SDEAs and evaluate that SDEAs is effective for use as artificial muscle application.

This is a multi-stacked Dielectric Elastomer Actuators. It is composed of the circular and plat Dielectric Elastomer. These are fabricated for Robot hand which made up with new type actuator.
Dielectric Elastomer
Actuation Principles
Electrostatic forces(Maxwell stress) between compliant electrodes provide pressure to deform dielectric elastomer
IPMC (Ionic Polymer-Metal Composites)
- Strain: 3%
