Yves Perriard, Yoan René Cyrille Civet, Stefania Maria Aliki Konstantinidi, Amine Benouhiba, Quentin Philippe Mario De Menech, Sloan Zammouri
Urinary incontinence (UI) is prevalent and distressing medical condition affecting millions of patients worldwide. Current treatment options for severe cases often involve surgical intervention, such as the implantation of an artificial urinary sphincter ( ...
Society of Photo-Optical Instrumentation Engineers (SPIE)2024Real-time actuation of a dielectric elastomer actuator neuroprosthesis for facial paralysis
Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Stefania Maria Aliki Konstantinidi, Armando Matthieu Walter, Amine Benouhiba
Facial paralysis is a highly burdening condition, resulting in a patient's inability to move his mimic musculature on one or both sides of his face. This condition compromises the patient's communication and facial expressions, and thus dramatically reduce ...
2023How to Make Elastomers Piezoelectric?
Piezoelectrics play a significant role in modern electronics and electric devices. Thermal or mechanical stress on such materials induces a change in polarization generating an electric response, which is the sole effect of why they are so interesting. How ...
WILEY2023Modeling and analysis of miniaturized magnetorheological valve for fluidic actuation
Fluidic actuation enables movement in a wide range of mechanical systems, from simple laboratory devices to more complex industrial machinery. Fluids are used to generate motion of mechanical pieces. The term "fluids" encompasses two types of technologies: ...
