Seven silicone rubber MRE samples with the same...

PURPOSE In the authors' experience, the color of silicone elastomer following polymerization in molds made of gypsum products is slightly different from the color that was matched in the presence of the patient, before the silicone is packed. It is hypothesized that the investing materials and separating media have an effect on the color during the polymerization process of the silicone. MATE...

Facial prosthetics has a long history that extends back to ancient man. The course of facial prosthetics has altered over time as improvement in surgical techniques and materials arrived. The need for facial prosthetics presumably also altered over time with social changes and changes in disease management. The past century has brought several remarkable changes that influenced the delivery of ...

Electrically tunable diffractive optical elements are presented based on two approaches: tunable and switchable DOE and DFB lasers based on holographically patterned LC-polymer composites and on surface relief gratings connected with dielectric elastomer actuator (DEA).

Most large-scale production processes in biotechnology are performed in fed-batch operational mode. In contrast, the screenings for microbial production strains are run in batch mode, which results in the microorganisms being subjected to different physiological conditions. This significantly affects strain selection. To demonstrate differences in ranking during strain selection depending on th...

We report a novel modification of silicone elastomer polydimethylsiloxane (PDMS) with a polymer graft that allows interfacial bonding between an elastomer and glass substrate to be performed without exposure of the substrate to harsh treatment conditions, such as oxygen plasma. Organic molecules can thus be patterned within microfluidic channels and still remain functional post-bonding. In addi...

Inchworm based on the voltage actuation of dielectric elastomer actuators (DEAs) are amongst the simplest types of robots. We demonstrate a proof-of-concept inchworm robot that incorporates a few aligned fibers to suppress undesirable actuator bulging and more effectively convert the bending of a dielectric elastomer unimorph to forward motion. Finite element modeling confirms the role of the f...

In this study, a magnetorheological elastomer (MRE) was manufactured and tested, and a MRE sandwich beam was also fabricated from a MRE between two thin aluminum layers. An experimental test rig was set up to investigate the vibration response of the MRE sandwich beam under a non-homogeneous magnetic field. The experimental results show that the first natural frequency of the MRE sandwich beam ...

The aim of this paper focused on obtaining the optimum cruciform geometry of reinforced magnetorheological elastomers (MRE) to perform homogeneous equibiaxial deformation tests, by using optimization algorithms and Finite Element Method (FEM) simulations. To validate the proposed specimen geometry, a digital image correlation (DIC) system was used to compare experimental result measurements wit...
