ACTUATORS USED FOR ARTIFICIAL MUSCLES [PDF]

open access: yesAnnals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2023
This work presents aspects regarding the actuators used to create artificial muscles and their operating principles. Actuators perform an action (movement, brightness increase, colour change) based on a stimulus (electrical, mechanical, magnetic or ...

Electro‐Powerless Balloon Soft Actuator with Manually Driven Fluidic Circuit

open access: yesAdvanced Electronic Materials, 2023
Balloon‐type actuators have attracted scientific attention because they allow easy control of the output intensity and a high degree‐of‐freedom regarding shape and movement. However, they require bulky external pumps and electric power suppliers.

An electrically actuated molecular toggle switch [PDF]

open access: yesNature Communications, 2017
Abstract Molecular electronics is considered a promising approach for future nanoelectronic devices. In order that molecular junctions can be used as electrical switches or even memory devices, they need to be actuated between two distinct conductance states in a controlled and reproducible manner by external stimuli.

Reduction of the vibration in a helicopter blade using piezoelectric actuators

open access: yesAviation, 2006
A method to reduce vibration in a helicopter blade under a variable harmonic pressure loading using piezoelectric actuators is presented. The model of a helicopter blade is an equivalent aluminum plate. To decrease the amplitude in the resonant frequency
