Urine-Contactless Device to Empty Bladders: an Ex-Vivo Proof-of-Concept Study in Porcine Bladders

Yves Perriard, Yoan René Cyrille Civet, Francesco Clavica

Current treatments for underactive bladder (UAB) have negative side effects, such as urinary tract infections, mainly because devices used for bladder emptying are in direct contact with urine (e.g. permanent or intermittent catheterisation). Moreover, mos ...

Impedance pumping as a non-invasive treatment for underactive bladder? An ex-vivo proof-of-concept-study in porcine bladders.

Yves Perriard, Yoan René Cyrille Civet, Francesco Clavica

In patients suffering from underactive bladder (UAB), the contraction of the detrusor muscle has insufficient strength or duration to ensure efficient bladder emptying. Although catheterisation is currently the most effective method to empty the bladder, i ...

Development of a biologically inspired in-vitro platform for long-term assessment of commercial and innovative ureteral stents

Yves Perriard, Yoan René Cyrille Civet, Francesco Clavica

Ureteral stents are small flexible tubes which are clinically used to restore the urine drainage in presence of obstructions of the ureteral lumen such as tumours, kidney/ureteral stones. The lifetime risk of developing urinary stones is about 20% in men a ...

Actuation Displacement Analysis of a Self-Switching Shape Memory Alloy Buckled Beam

Yves Perriard, Yoan René Cyrille Civet, Morgan Almanza, Sean Thomas

This paper aims to simulate using Finite Element Modelling (FEM), a self-activating bistable buckled beam actuator using SMAs. In this work, various parameters such as the dimensions of the beam, shape geometry are studied to determine their effects on the ...

Sensorless Position Detection Framework for a Multi-state Switched Reluctance Actuator of a Textile Machine

Yves Perriard, Yoan René Cyrille Civet, Paolo Germano, Xinchang Liu

Sensorless needle position detection for the actuator of a textile machine is challenging because of its multi current levels used and the transient state when the current changes. A local regression method can be used to represent the variation of inducta ...

Energy analysis of a DEAP based cylindrical actuator coupled with a radial negative stiffness spring

Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne

The main problem to obtain considerable deformation with dielectric electro-active polymer based technology is the electrical breakdown. A simple solution consists in pre-stretching the elastomer before activating it which cancels the snap-through effect a ...
