Area of Science:

  • Materials Science
  • Polymer Science
  • Robotics

Background:

  • Liquid crystal elastomers (LCEs) are promising for actuators but often require external heating or light.
  • Existing electroactive LCEs are limited and typically monofunctional (bending or contraction).

Purpose of the Study:

  • To develop a bi-functional electroactive LCE (eLCE) capable of both bending and contraction.
  • To combine LCE technology with ionic electroactive polymer devices (i-EADs) for enhanced performance.

Main Methods:

  • Fabrication of a trilayer eLCE by integrating LCE and i-EAD.
  • Applying low-voltage stimulation (±2 V at 0.1 Hz) to induce bending via redox behavior and ionic motion.
  • Applying higher voltage (±6 V at 10 Hz) to trigger muscle-like contraction through Joule heating.

Main Results:

  • Achieved a bending strain difference of 0.80% with ±2 V stimulation.
  • Demonstrated muscle-like linear contraction up to 20% strain with ±6 V stimulation.
  • Enabled the eLCE to lift 270 times its weight with 20% strain and a work capacity of 5.38 kJ·m⁻³.

Conclusions:

  • The novel trilayer eLCE exhibits bi-functional actuation (bending and contraction) under low-voltage control.
  • This approach integrates LCE and i-EAD technologies for multi-degree-of-freedom smart materials.
  • The developed eLCE shows significant potential for soft robotics, electronic devices, and sensors.
