OBJECTIVE To examine the usefulness of room temperature vulcanizing (RTV) silicone rubber as a barrier material for cell exclusion zone assays. METHODS We created barriers using three types of RTV silicone rubber with differing viscosities. We then assessed the adherence of these barriers to culture dishes and their ease of removal from the dishes. We tested the effect of the newly created ba...

A teletaction system uses a tactile display to present the user with information about texture, local shape, and/or local compliance. Current tactile displays are at and rigid, and require precise machining and assembly of many parts. This paper describes the fabrication and performance of a one-piece pneumaticallyactuated tactile display molded from silicone rubber. Tactor spacing is 2.5 mm wi...

A multitude of various materials are available for the visualization of cadaveric vessels, ranging from natural materials like gelatin and latex to synthetic materials like silicone rubber or acrylates. To achieve a detailed overview of the vascular architecture in microvascular studies in experimental flap surgery, the injected material should have low viscosity to assure perfusion of even the...

Medical simulators that allow the user to explore and manipulate artificial tissue with the bare hand require simultaneous control of geometry and mechanical properties of physical surfaces. We present a novel haptic display that forms controllable lumps at various locations on a surface, a feature that could prove useful for simulating palpation tasks. The lumps are created by controlling posi...

Twelve monkeys, Macaca fascicularis and Macaca mulatta, were investigated to study their renal microvasculature. After death, all monkeys were perfused with heparinised isotonic saline to flush their vascular systems. The kidneys were then perfused with silicone rubber and examined. The silicone rubber injections allowed description of afferent arterioles and several efferent vascular patterns ...

Conductive silicone rubber has great advantages for strain sensing applications. The electrical behavior of the elastomeric material is rate-dependent and exhibit hysteresis upon cyclic loading. Several constitutive models were developed for mechanical simulation of this material upon loading and unloading. One of the successful approaches to model the time-dependent behavior of elastomers is B...

Two quaternary ammonium silanes (QAS) were used to coat silicone rubber tracheoesophageal shunt prostheses, yielding a positively charged surface. One QAS coating [(trimethoxysilyl)-propyldimethyloctadecylammonium chloride] was applied through chemical bonding, while the other coating, Biocidal ZF, was sprayed onto the silicone rubber surface. The sprayed coating lost its stability within an ho...

PURPOSE At St. Erik Eye Hospital in Stockholm, Sweden, ocular tumors of apical height above 6 mm are treated with brachytherapy, using iodine-125 seeds attached to a gold alloy plaque while the treatment planning is performed assuming homogeneous water surroundings. The aim of this work was to investigate the dose-modifying effects of the plaque and the seed fixating silicone rubber glue. MET...

In recent years, soft pipeline robot, as a new concept, is proposed to adapt tunnel. The robots are made of materials such rubber or silicone. These have good elasticity, which enhance the adaptability robot. Therefore, robot has better performance on deformability than rigid However, structure tunnel complex and varied that brought challenges design this paper, we propose with simple easy fabr...

OBJECTIVES Maxillofacial prosthetic materials are used to replace facial parts lost through disease or trauma. Silicone rubbers are the materials of choice, however it is widely accepted that these materials do not possess ideal properties. The objective of this study was to assess the properties of a range of commercially available silicone rubber maxillofacial materials and make recommendatio...
