The Dielectric Elastomer Sensor (DES) offers real-time pressure and vibration monitoring in soft fluidic actuators, ideal for robotics and biomedical devices. The sensor's flexibility and ability to withstand large deformations make it suitable for applications in automobile designing and structural health monitoring.
Researchers at MIT have developed a new generation of tiny, agile drones that can operate in cramped spaces and withstand collisions. The drones use soft actuators to mimic insect flight, allowing them to flap their wings nearly 500 times per second and navigate complex environments with high agility.
Electrochemically driven carbon nanotube muscles contract more when driven faster, solving limitations that restricted their applications. The polymer coating used in the study converts bipolar actuation to unipolar, making the muscles faster and more powerful.
A team of researchers from Fraunhofer Techologie-Entwicklungsgruppe has developed a measurement device to analyze the electromechanical properties of bucky paper actuators. The study provides insights into the actuation mechanism of carbon nanotubes and suggests future directions for research.
Scientists have developed sheets of single-walled nanotubes that generate higher stresses than natural muscle and higher strains than high-modulus ferroelectrics. The carbon nanotube actuators work in aqueous environments, including salt water, and require small voltages to produce large length changes.
