In addition, LCPs have unique properties like thermal actuation, anisotropic swelling, and soft elasticity. Therefore, they can be good actuators and sensors. [ 4 ] One of the most famous and classical applications for LCPs is Kevlar , a strong but light fiber with wide applications, notably bulletproof vests .
Diaphragm actuators: A diaphragm actuator is made as a planar construction which is then biased in the z-axis to produce out of plane motion. Shell-like actuators: Planar elastomer films are coated at specific locations in the form of electrode segments. With a well-directed activation, the foils assume complex three-dimensional shapes.
A soft actuator is made of a flexible material that changes its shape in response to stimuli including mechanical, thermal, magnetic, and electrical. Soft actuators mainly deal with the robotics of humans rather than industry which is what most of the actuators are used for.
The maximum actuator strain for electrically driven actuators of carbon nanotube sheets can be improved up to 0.7% in a 1 M electrolyte once the sheets are annealed in an inert atmosphere at very high temperatures (1,100 °C, 2,000 °F) in contrast to once-reported 0.1% or less for low electrochemical potentials (≈1 V or less).

Since these materials exhibit excellent electroactive character, EAP materials show potential in biomimetic-robot research, stress sensors and acoustics field, which will make EAPs become a more attractive study topic in the near future. They have been used for various actuators such as face muscles and arm muscles in humanoid robots. [38]
A soft exoskeleton, also known as a soft wearable robot or a soft robotic exosuit, is a type of wearable robotic device designed to augment and enhance the physical abilities of the human body. Unlike traditional rigid exoskeletons , which are typically made of hard materials like metal and are worn over the user's limbs, soft exoskeletons are ...
