Retention and associated fish mortality of visible implant alphanumeric (VIA) and fluorescent elastomer tags was assessed in 2 Australian intertidal rockpool fishes, Girella elevata (Girellidae) and Bathygobius cocosensis (Gobiidae). Mean retention of VIA and elastomer tags after 90 d was 32 ± 20% and 77 ± 19%, respectively. After 90 d the fish mean mortality from VIA tags (20 ± 5%) was signifi...

This paper studies the collapse of a void in an elastomer caused by osmosis. The void is filled with liquid water, while the elastomer is surrounded by unsaturated air. The difference in humidity motivates water molecules to permeate through the elastomer, from inside the void to outside the elastomer, leaving the liquid water inside the void in tension. When the tension is low, the void reduce...

Dielectric elastomer is one of the new types electronic materials that have both drive ability and electric generating capacity. In this research, fundamental tests were performed to evaluate abilities of dielectric elastomer. As the result, it was found that dielectric elastomer had very efficient drive ability and electric generating capacity, and that it was applicable to both slow and high ...

Inspired by mammalian skins, soft hybrids integrating the merits of elastomers and hydrogels have potential applications in diverse areas including stretchable and bio-integrated electronics, microfluidics, tissue engineering, soft robotics and biomedical devices. However, existing hydrogel-elastomer hybrids have limitations such as weak interfacial bonding, low robustness and difficulties in p...

This paper reports dimensional dependence of the mechanical response in carbon nanostructure composites to near-infrared (NIR) light. Using polydimethylsiloxane, a common silicone elastomer, composites were fabricated with one-dimensional multi-wall carbon nanotubes (MWNTs), two-dimensional single-layer graphene, two-and-a-half-dimensional graphene nanoplatelets and three-dimensional highly ord...

A method of measuring the volume of the human dental pulp cavity is described. The crown of an extracted tooth is divided from its root. .After cleaning the pulp cavity, it is filled with an elastomer, and the fractured tooth surfaces repositioned before the elastomer sets. The tooth is corroded in acid to release the elastomer which is then weighed, and its volume calculated. The method has be...

In recent years, soft pneumatic actuators have come into the spotlight because of their simple control and wide range complex motions. To monitor deformation robotic systems, elastomer-based sensors are being used. However, embedding actuator modules by polymer casting is time consuming difficult to upscale. this study, it shown how a bending with an integrated sensing element can be produced u...

A unique way of robustly integrating an elastomer fi lm onto a graphitic anode and then post-process it into a solid-state electrolyte for lithium-ion battery applications is reported. The mutual solvability of the elastomer and the binder of the graphitic anode (carboxymethyl cellulose, (CMC)) in dimethylformamide facilitates the fusion of the two heterogeneous layers. Dimensional dynamics evo...
