Abstract
A great amount of effort has been devoted to the constant improvement of such basic automobile performance as drivability, safety, and environmental protection. As a result, the total combination of various technologies has made it possible to produce safer and more comfortable automobiles. Among these technologies, surface and thin film techniques are mainly concerned with sensors, optics, electronics and surface modification. This article first describes a new concept of thin film processing in materials synthesis for sensors based on particle–surface interaction during deposition to provide a long life sensor applicable to automobiles. Some examples of practical applications of thin films to sensors are then given. These include (1) a poly(vinylidene fluoride) thin film for integrated pyroelectric infrared sensors, (2) a thin film strain gauge for gravity sensors, and (3) a giant magnetoresistance film for speed sensors.
