In this paper a semi cylindrical fluid filled hyperelastic finger model for soft contact has been developed from the basic principles of mechanics. The deformation parameters namely contact width and radial deflection were calculated for different applied forces. To validate this analytical model, compression tests were conducted on silicone rubber finger specimens . Contact width and radial deflection were also calculated using Mooney-Rivlin, Ogden and Neo Hookean theories and compared with the analytical results. It has been found that , the analytical model deformation results are more agreeable with the experimental finger results.
