Highly deformable, soft elastic, viscoelastic and poroelastic materials occur in many different applications e.g. soft tissues, artificial organs, therapeutic patches, shock absorbers, dampeners, platforms for micro-fluidic device, novel biomaterials in biology as stems, roots and leaves, sponges, cartilage layers and bones and so on and so forth. In this variety of situations these materials are exposed to many different forms of mechanical loads, e.g. tension, compression, torsion, bending which, due to the large deformability of these materials and their complex rheological character, can generate such responses which are different from that commonly observed with the liner elastic systems. An example of such a response is the kinking instability in a cylindrical rod of soft hydrogel, bent beyond a critical curvature. It is different from the commonly observed wrinkling instability. Besides, we have recently developed a microfluidic adhesive by embedding microchannels inside adhesive layers. By filling these channels with liquids we have shown that adhesion strength can be enhanced significantly. Our research on microfluidics has led to the development of a simple technique for generating complex 3D microstructures inside soft polymeric materials which have many potential applications, e.g. we have developed a novel multi-helical microfluidic mixer for rapid mixing of liquids.
