Liquid Crystal Elastomer (LCE) Fiber: A Material with the Potential to Revolutionize Industries

Updated: Nov 26, 2023

Liquid crystal elastomer (LCE) fiber is a smart nano-material that can change its shape in response to stimuli such as temperature, light, or electricity. This unique property makes LCE fibers ideal for a wide range of applications, including artificial muscles, sensors, and actuators. Currently, EntangledVibrations.com is working with start-ups on this innovation.


Liquid crystal elastomer (LCE) fibers are made from a combination of liquid crystals and elastomers, which are materials that can stretch and return to their original shape. When an LCE fiber is exposed to a stimulus, the liquid crystals align themselves in a different way, causing the elastomer to stretch or contract. This makes LCE fibers ideal for a variety of applications, including artificial muscles, sensors, and actuators reported CEO, James Dean.


Properties of LCE Fiber


LCE fibers are characterized by several key properties that make them attractive for a variety of applications:

  • High strain: LCE fibers can undergo large deformations, up to 400% of their original length. This makes them ideal for applications where large movements are required, such as artificial muscles.

  • Fast response time: LCE fibers can change their shape in a matter of milliseconds. This makes them ideal for applications where rapid response is required, such as sensors and actuators.

  • Biocompatibility: LCE fibers are biocompatible and can be used in medical applications. This is due to their non-toxic nature and their ability to be sterilized.

  • Sustainability: LCE fibers can be made from renewable resources. This makes them an environmentally friendly option for a variety of applications at low cost.


Applications of LCE Fiber


Due to their unique properties, LCE fibers have the potential to revolutionize a variety of industries, including:

  • Artificial muscles: LCE fibers can be used to create artificial muscles that can power robots and other devices. This is because LCE fibers can contract and expand in response to stimuli, mimicking the behavior of natural muscles.

  • Sensors: LCE fibers can be used to create sensors that can detect changes in temperature, pressure, and other stimuli. This is because LCE fibers can change their shape in response to these stimuli, which can be detected by measuring changes in electrical resistance, temperature or light transmission.

  • Actuators: LCE fibers can be used to create actuators that can move objects or control devices. This is because LCE fibers can contract and expand in response to stimuli, which can be used to generate force or movement.

  • Marine Underwater: Many valuable LCE fiber applications exist to provide advanced solutions including ocean wave energy, vessel ship self-healing coating, environmental sensors and exploratory robotics. Watch Video


Let's take for example, the space exploration applications for liquid crystal elastomer (LCE) fibers which have the potential to revolutionize the industry in several ways:


1. Deployable Structures: LCE fibers can be used to create lightweight, compact, and deployable structures for space applications. These structures can be folded or rolled up for storage and then deployed when needed. For example, LCE fibers could be used to create deployable solar sails, antennas, or habitats.


2. Adaptive Materials: LCE fibers can be used to create adaptive materials that can change their shape or properties in response to stimuli. This could be used to create self-healing structures that can repair themselves in the harsh environment of space. For example, LCE fibers could be used to create a self-healing spacecraft skin that could repair itself from micrometeoroid impacts.


3. Soft Robotics: LCE fibers can be used to create soft robots that are flexible and adaptable. This could be used to create robots that can explore hazardous environments or perform delicate tasks. For example, LCE fibers could be used to create a soft robot that can navigate through asteroid fields or perform repairs on spacecraft.


4. Actuators and Sensors: LCE fibers can be used to create actuators and sensors for space applications. Actuators can be used to move objects or control devices, while sensors can be used to detect changes in the environment. For example, LCE fibers could be used to create a gripper for manipulating objects in space or a sensor for detecting radiation levels.

Here are some specific examples of how LCE fibers could be used in space exploration:

  • A self-deploying solar sail made from LCE fibers could be used to propel a spacecraft to distant stars.

  • An adaptive habitat made from LCE fibers could change its shape to accommodate different numbers of astronauts or to protect itself from radiation.

Further, liquid crystal elastomer (LCE) fibers are a promising material for a variety of marine underwater applications, due to their unique properties of high strain, fast response time, biocompatibility, and sustainability.

Underwater Actuators and Robotics:


LCE fibers can be used to create actuators that can move objects or control devices underwater. This could be used to create underwater robots that are more flexible and adaptable than traditional robots, which are often limited by their rigid bodies. For example, LCE fibers could be used to create a soft robotic gripper that can manipulate objects in the deep sea or a soft robotic arm that can assist divers with tasks.


Underwater Sensors:

LCE fibers can be used to create sensors that can detect changes in the underwater environment. This could be used to create sensors for measuring temperature, pressure, salinity, and other parameters. For example, LCE fibers could be used to create a sensor for detecting underwater currents or a sensor for monitoring the health of coral reefs.


Self-Healing Coatings:

LCE fibers can be used to create self-healing coatings that can protect underwater structures from corrosion and damage. This is because LCE fibers can change their shape in response to stimuli, which could be used to close up cracks or seal holes in a coating. For example, LCE fibers could be used to create a self-healing coating for an underwater pipeline or a self-healing coating for a submarine hull.


Biofouling Mitigation:

LCE fibers can be used to create surfaces that are resistant to biofouling, which is the buildup of marine organisms on underwater surfaces. This is because LCE fibers can change their surface properties in response to stimuli, which could be used to prevent marine organisms from attaching to the surface. For example, LCE fibers could be used to create a biofouling-resistant coating for an underwater sensor or a biofouling-resistant coating for a ship's hull.


Marine Energy Harvesting:

LCE fibers can be used to create devices that can harvest energy from the ocean. This is because LCE fibers can convert mechanical energy into electrical energy. For example, LCE fibers could be used to create a wave energy converter that converts the sustainable clean energy of ocean waves into electricity that may power millions of communities worldwide.


While medical healthcare applications of liquid crystal elastomer (LCE) fibers allow biotech researchers to revolutionize the field of synthetic skin, offering a number of advantages over traditional silicone-based materials.


Enhanced Sensory Perception: LCE fibers can be engineered to incorporate sensory capabilities, allowing synthetic skin to detect changes in temperature, pressure, and other stimuli. This could enable prosthetic limbs to provide users with a more natural sense of touch, or allow artificial skin to be used in wearable devices for monitoring health and environmental conditions.

Self-Healing Properties: LCE fibers can be designed to possess self-healing capabilities, enabling synthetic skin to repair itself from minor damage. This could significantly extend the lifespan of prosthetics and other synthetic skin applications, reducing the need for frequent replacements.

Biocompatibility and Permeability: LCE fibers can be tailored to be biocompatible and permeable, allowing for better integration with the human body and facilitating exchange of gases and fluids. This could improve the comfort and longevity of synthetic skin implants and reduce the risk of infections.


Shape-Changing Capabilities: LCE fibers can be actuated to change their shape, enabling synthetic skin to mimic natural skin's ability to form wrinkles, folds, and other expressions. This could enhance the realism of prosthetics and artificial skin used for cosmetic purposes.



Applications of LCE Fiber in Synthetic Skin:
