Electropolymerized Conducting Polymer as Actuator and Sensor Device: An Undergraduate Electrochemical Laboratory Experiment  María T. Cortés and Juan C. Moreno
A trilayer formed by two conducting polymer films sandwiched around an adhesive polymer layer works as actuator and sensor simultaneously. This device can be bent up to 180 and it can be used as a sensing device of physical chemistry parameters such as cell temperature and electrolyte concentration. In this article, it is shown in a didactic way how to electrochemically synthesize ClO4-doped polypyrrole (PPy) films, how to fabricate a trilayer device, and how to evaluate its actuating and sensing capabilities. The required materials are simple and a complicated setup is not necessary.

Slide Projector Corrosion Cell  Silvia Tejada, Estela Guevara, and Esperanza Olivares
The process of corrosion can be demonstrated in a slide projector, since the cell is in the shape of a slide, or on the stage of an overhead projector by setting up a simple galvanic cell. Corrosion occurs as the result of a galvanic cell reaction, in which the corroding metal acts as the anode. Several simple demonstrations relating to corrosion are described here.
