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.

Introduction to Photolithography: Preparation of Microscale Polymer Silhouettes  Kimberly L. Berkowski, Kyle N. Plunkett, Qing Yu, and Jeffrey S. Moore
In this experiment, a glass microscope slide acts as the microchip. Students can pattern this "microchip" by layering negative photoresist on the slide using a solution containing monomer, crosslinker, photoinitiator, and dye. The students then cover the photoresist with a photomask, which is the negative of a computer-generated image or text printed on transparency film, and illuminate it with UV light. The photoresist in the exposed area polymerizes into a polymer network with a shape dictated by the photomask. The versatility of this technique is exemplified by allowing each student to fabricate virtually any shape imaginable, including his or her silhouette.
