A hybrid beam with a gel layer bonded on the top of an elastic non-swellable substrate has been commonly adopted to make various sensors and actuators. Usually, different models need to be developed for the hybrid beam when different gels are used in the system. In this article, based on the generalized ideal elastomeric gel model, we formulate a unified relationship between the swelling of hydrogels and the bending curvature of the elastic beam, which is independent of specific swelling mechanisms of gels. We further illustrate that the equations derived in the article can be used to validate the ideal elastomeric gel model and measure the elasticity of polymer networks of the gels.
一种在弹性不可溶胀基底顶部粘结有凝胶层的混合梁已被广泛用于制造各种传感器和致动器。通常,当系统中使用不同的凝胶时,需要为混合梁开发不同的模型。在本文中,基于广义理想弹性体凝胶模型,我们建立了水凝胶溶胀与弹性梁弯曲曲率之间的统一关系,该关系与凝胶的具体溶胀机制无关。我们进一步说明,本文推导的方程可用于验证理想弹性体凝胶模型并测量凝胶聚合物网络的弹性。
