There is not always a clear distinction between Type I and Type II systems. Section II of this volume addresses several works with gels. In some cases the nonlinearities of the gel also play a role. The extreme case is the system developed by Siegel. He and his colleagues utilized the hysteresis in a hydrogel s permeability to create autonomous chemomechanical oscillations in a hydrogel/enzyme system driven by glucose 49,50), This is also addressed in chapter 4.
