Tactile sensors and electrotactile stimulators can provide important links between humans and virtual environments, through the sensation of touch. Soft materials, such as low modulus silicones, are attractive as platforms and support matrices for arrays sensors and actuators that laminate directly onto the fingertips. Analytic models for the mechanics of three dimensional, form-fitting finger ...

This letter is in response to the summary of the safety assessment of the Scientific Committee on Consumer Safety (SCCS) on decamethylcyclopentasiloxane (D5) in cosmetic products published (SCCS & Rousselle, 2017) and the opinion (SCCS, 2017). We have been asked by the Silicones Environmental, Health and Safety Center of the American Chemistry Council to provide comments given that SCCS (2017) ...

The color stability of polyvinyl chloride, polyurethane, and silicone polymers for maxillofacial applications was determined after accelerated aging using reflectance spectrophotometry. On the basis of color stability after accelerated aging, and ease of processing, several silicone materials were the most promising.

The dynamic viscoelastic properties of long-term soft denture liners were measured over a wide range of frequencies using a dynamic viscoelastometer based on a non-resonance-forced vibration principle. Changes in properties over a 3 yr period have also been monitored. One acrylic material, one fluoroelastomer, one heat cured silicone and one self-curing addition silicone were used. Complex dyna...

BACKGROUND Attachment strength of fouling organisms on silicone coatings is low. We hypothesized that low attachment strength on silicones is, in part, due to the interaction of surface available components with natural glues. Components could alter curing of glues through bulk changes or specifically through altered enzyme activity. METHODOLOGY/PRINCIPAL FINDINGS GC-MS analysis of silicone c...
