Investigation of Self-Sensing Techniques for Dielectric Elastomer Actuators
Self-sensing allows to use a Dielectric Elastomer Actuator (DEA) simultaneously as an actuator and sensor, without the need of external sensors. DEAs are composed of a dielectric elastomer that is sandwiched between two electrodes. If a voltage difference ...
2023Leveraging the Snap Buckling of Bistable Magnetic Shells to Design a Refreshable Braille Dot
Pedro Miguel Nunes Pereira de Almeida Reis, Tian Chen, Arefeh Abbasi, Bastien Freddy Gustave Aymon
A design concept is proposed for the building block, a dot, of programmable braille readers utilizing bistable shell buckling, magnetic actuation, and pneumatic loading. The design process is guided by Finite Element simulations, which are initially valida ...
Hoboken2023Rock-Flow Cell Parameters Evaluation Using Ultrasound Doppler Velocimetry
Giovanni De Cesare, Javier Neves da Silva, Andre Luis Stakowian
This work presents a study of two-phase flow generated inside a rock-flow cell setup. It is characterized by a pipe section filled with fluid (oil in our studies) that is put into oscillation around its mass centre by an electric motor. This type of appara ...
