E SC 122S Weird, Wild, and Wonderful Materials and Devices (1)
There are many materials whose response to a particular stimulus (mechanical, thermal, electrical, etc.) is of a completely different type. For example, if a piezoelastic material is mechanically "squeezed" (stimulus) the response is the creation of an electrical signal. Birefringent (photoelasticity) materials change their optical properties under mechanical displacement. Thermoluminesent "remember" their configuration under certain environmental combinations, to which they will abruptly return when these same combinations are repeated. This seminar surveys many classes of such materials and material systems and provides examples of engineers utilizing their behavior for sensors, transducers, and actuators. Examples include acoustic refrigerators, phonograph cartridges, door openers, and stress concentration locators.
