Repetitive regime of highly focused liquid microjets for needle-free injection

Christophe Moser, Paul Delrot, Jan Krizek

Fast liquid jets are investigated for use as a needle-free drug delivery system into an elastic tissue such as skin. Using smaller jet diameters in a repetitive regime can mitigate bruising and pain associated with current injectors. In this study, we aim ...

A hybrid control strategy for force and precise end effector positioning of a twisted string actuator

Jamie Paik, Andres San Millan Rodriguez, Mohssen Fischer

We propose a new control approach for the twisted string actuation (TSA) system; a hybrid control scheme consisting of two nested loops, considering the motor angle and the axial force at the clamping point of the actuator as the system outputs. We show th ...

Injection Device

Yves Perriard, Romain David Besuchet

An injection deviee for injecting injection material, comprising: an elastic deformable element (3) able to exert a pushing force on a piston (20) of a syringe (2) so as to eject a quantity of injection material out of the syringe (2); a stopper ( 4) for r ...

Hydrodynamics of High Specific Power Pumps for Off-Design Operating Conditions

Part load operation of high energy centrifugal pumps is associated with increased vibration levels which may adversely affect the machines operational safety. The main sources of vibrations in centrifugal pumps are of hydrodynamic nature. The interaction b ...

Experiments in a novel quasi-1D diffusion flame with variable bulk flow

Peter Monkewitz, Etienne Robert

The novel species injector of a recently developed research burner, consisting of an array of hypodermic needles, which allows to produce quasi one-dimensional unstrained diffusion flames has been improved. It is used in a new symmetric design with fuel an ...

Experimental investigation of unstrained diffusion flames and their instabilities

Etienne Robert

In this thesis, thermal-diffusive instabilities are studied experimentally in diffusion flames. The novel species injector of a recently developed research burner, consisting of an array of hypodermic needles, which allows to produce quasi one-dimensional ...

Mechanical characterization of a dielectric elastomer microactuator with ion-implanted electrodes

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We report on the mechanical characterization and modeling of a non-prestretched dielectric elastomer diaphragm microactuator with ion-implanted electrodes under the influence of a distributed load (pressure). Thin polydimethysiloxane (PDMS) membranes (30 u ...
