Since 2012, when triboelectric nanogenerators (TENGs) were first reported by Wang and co-workers, various applications have taken advantage of their ability to transform mechanical energy into electrical energy. TENG applications cover many fields, including electronics, physics, materials science, and engineering. The differences in the language…

Lecture-based experimental methods that include topics ranging from basic signal processing to the proper use of thermocouples to advanced optical techniques such as laser-induced fluorescence are described. The data obtained from this demonstration could be provided to the students in digital form to obtain useful engineering results such as an…

A rapid scanning polargraph, constructed from inexpensive parts, which can delay voltage scan for a predetermined length of time, is described. Schematic diagram of the instrument is included. Uses of the instrument are described. (MR)

An experiment in rapid scanning polargraphy using the Health Polargraph System is described. The experiment was designed to be used in an undergraduate course on instrument analysis. The theory, instruments, and results of the experiment are also discussed. (MR)
