TL;DR: When tissue cells are cultured on very thin sheets of cross-linked silicone fluid, the traction forces the cells exert are made visible as elastic distortion and wrinkling of this substratum.
Abstract: When tissue cells are cultured on very thin sheets of cross-linked silicone fluid, the traction forces the cells exert are made visible as elastic distortion and wrinkling of this substratum. Around explants this pattern of wrinkling closely resembles the "center effects" long observed in plasma clots and traditionally attributed to dehydration shrinkage.

TL;DR: Polydimethylsiloxane (PDMS) is a commercially available physically and chemically stable silicone rubber as mentioned in this paper, which has a unique flexibility with a shear elastic modulus due to one of the lowest glass transition temperatures of any polymer.
Abstract: Polydimethylsiloxane (PDMS) is a commercially available physically and chemically stable silicone rubber. It has a unique flexibility with a shear elastic modulus due to one of the lowest glass transition temperatures of any polymer . Further properties of PDMS are a low change in the shear elastic modulus versus temperature , virtually no change in G versus frequency and a high compressibility. Because of its clean room processability, its low curing temperature, its high flexibility, the possibility to change its functional groups and the very low drift of its properties with time and temperature, PDMS is very well suited for micromachined mechanical and chemical sensors, such as accelerometers (as the spring material) and ISFETs (as the ion selective membrane). It can also be used as an adhesive in wafer bonding, as a cover material in tactile sensors and as the mechanical decoupling zone in sensor packagings.

TL;DR: A superhydrophobic fabric coating made of a crosslinked polydimethylsiloxane elastomer, containing well-dispersed hydrophobic silica nanoparticles and fluorinated alkyl silane shows remarkable durability against repeated machine washes, severe abrasion, strong acid or base, boiling water or beverages and excellent stain resistance.

TL;DR: The present study finds a "viscosity" that would maintain the "clarity" of the vitreous of rabbits and help in "replacing the retina" in plastic surgery and retinal detachment procedures.
Abstract: Introduction Silicone rubber has been widely used as implant material in plastic surgery and in retinal detachment procedures. 1 Liquid silicone was first injected into the vitreous cavity of rabbits by Stone, 2 who reported that silicone fluids of various viscosities were well tolerated and produced "very little change in the rabbit eyes over a period of two years." He went on to predict that it might be possible to find a "viscosity" that would maintain the "clarity" of the vitreous and help in "replacing the retina." Recently, other investigators 3-5 have confirmed Stone's observations. However, their animal experiments emphasized the possibilities of complications. Everett 4 reported cataract formation following the injection of liquid silicone into the vitreous cavity of rabbits; Galavin 5 produced glaucoma by the injection of liquid silicone into the posterior chamber of the rabbit eye. The present study serves a dual purpose: (1) to report further

TL;DR: In this article, a hyperelastic pressure transducer is fabricated by embedding silicone rubber with microchannels of conductive liquid eutectic gallium-indium.
Abstract: A hyperelastic pressure transducer is fabricated by embedding silicone rubber with microchannels of conductive liquid eutectic gallium–indium. Pressing the surface of the elastomer with pressures in the range of 0–100 kPa will deform the cross-section of underlying channels and change their electric resistance by as much as 50%. Microchannels with dimensions as small as 25 µm are obtained with a maskless, soft lithography process that utilizes direct laser exposure. Change in electrical resistance is measured as a function of the magnitude and area of the surface pressure as well as the cross-sectional geometry, depth and relative lateral position of the embedded channel. These experimentally measured values closely match closed-form theoretical predictions derived from plane strain elasticity and contact mechanics.
