Abstract– Different from the traditional rigid robots made by hard material such as metal, continuum robots are bionic mechanisms which feature high compliance and continuous shapechanging ability. A full compliant continuum robotic finger is proposed, which is driven by the compressed air inside its silicon rubber chamber and has a certain degree of grasping rigidity. By the moment equilibrium...

Rotating bioreactors such as the High Aspect Ratio Vessel (HARV) provide a low shear and gentle mixing environment, ideal for mammalian cell culture in 3D. The HARV is a cylindrical “disc-shaped” batch culture vessel with no internal moving parts, that rotates about a single axis. Oxygenation is provided by a permeable silicon rubber membrane, allowing the diffusion of gases to and from the med...

Soft contact lamination of source/drain electrodes supported by gold-coated high-resolution rubber stamps against organic semiconductor films can yield high-performance organic transistors. This article presents a detailed study of the electrical properties of these devices, with an emphasis on the nature of the laminated contacts with the pand n-type semiconductors pentacene and copper hexadec...

Useful lifetime evaluation of chevron rubber spring was very important in design procedure to assure the safety and reliability. It is, therefore, necessary to establish a suitable criterion for the replacement period of chevron rubber spring. In this study, we performed characteristic analysis and useful lifetime prediction of chevron rubber spring. Rubber material coefficient was obtained by ...

In order to calculate deformation of soft tissue under arbitrary loading conditions, we have to take both non-linear material characteristics and subcutaneous structures into considerations. The estimation method of material properties presented in this paper accounts for these issues. It employs a compression test inside MRI in order to visualize deformation of hypodermic layered structure of ...

Natural rubber (cis-1,4-polyisoprene) is an isoprenoid compound produced exclusively in plants by the action of rubber transferase. Despite a keen interest in revealing the mechanisms of rubber chain elongation and chain length determination, the molecular nature of rubber transferase has not yet been identified. A recent report has revealed that a 24 kDa protein tightly associated with the sma...

Rubber is the most widespread smallholder tree crop in South-East Asia. Although initially large estates planted the bulk of the region’s rubber, smallholders soon captured most of the production. Currently, Indonesia’s rubber plantations cover 3.4 million ha, of which smallholders account for more than 75% (BPS, 1999). In peninsular Malaysia, the area in rubber has declined since the 1970s, bu...

Rubber dams are inflatable and deflatable hydraulic structures. Thousands of rubber dams have been installed worldwide for various purposes: irrigation, water supply, power generation, tidal barrier, flood control, environmental improvement, and recreation. Furthermore, rubber dams have been used in cold areas where the temperature is as low as –40°C. The simplicity and flexibility of the rubbe...
