聚合物凝胶是非常有前途的实现自主功能的物理或化学刺激的装置。因为它们也可以用作构建非常便宜的设备的基本构建块，所以作者使用聚合物凝胶来构建用于测量葡萄糖浓度的微致动器。在微型泵中，通过改变温度来抽取外部溶液。采样时间也可通过酶促反应引起的pH变化进行调整。相同的机制可以应用于构建自发功能的生物传感器，通过该生物传感器，可以从液柱长度的变化测量葡萄糖浓度。
Polymer gels are very promising for the realization of devices which function autonomously in response to physical or chemical stimuli. Because they can also be used as basic building blocks in constructing very inexpensive devices, the authors have used polymer gels to construct microactuators for use in measuring glucose concentrations. In a micropump, an external solution is withdrawn by changing the temperature. The sampling time is also adjusted by using a pH change caused by an enzymatic reaction. The same mechanism can be applied to the construction of a spontaneously functioning biosensor, through which glucose concentrations can be measured from changes in length of the liquid column.
