水凝胶是由亲水性高分子链组成的网络，它可以在不溶解的情况下与大量的水结合。由于其成分的性质，主要是水，它具有很高的生物相容性。凝胶的聚合链可以被设计成对材料具有广泛的性能，如环境响应、机械性能和化学性能。水凝胶为各种组织工程应用（细胞培养或细胞接种的三维支架、细胞包埋、纳米颗粒等）的发展提供了非常有趣的平台，并找到了新的微流体和个人诊断设备。这些水凝胶的发展需要表征其力学性能。

A hydrogel is constituted of a network of hydrophilic polymeric chains that can associate with large quantity of water without dissolving. Due to the nature of its composition, being mostly water, it has a high biocompatibility. The polymeric chains of the gel can be engineered to give a wide spectrum of capabilities to the material such as environmental response, mechanical properties and chemical properties. Hydrogels make very interesting platforms for the development of various tissue engineering applications (3D scaffold for cell culture or cell seeding, cell encapsulation, nanoparticles, etc.) and find their way to new microfluidics and personal diagnostic devices. The development of those hydrogels requires precise characterization of their mechanical properties.
