Abstract

Many materials, particularly high tech plastics and composites used in aircraft and boats, suffer from damage due to prolonged ultraviolet exposure. This damage may not be evident until the material has been seriously degraded to the point of failure.Researchers at Arizona State University have developed a simple and inexpensive method of measuring the cumulative UV dose at various points on the surface of a component (e.g. a wing or a hull). This new development is based on research in U.S. Patent Number 5,500,532 (1996) "Personal Electronic Dosimeter" conducted at ASU. It utilizes resistance change in photo-dissolvable metals. There need be no permanent electrical connection to the elements. Cumulative dose may be "read" by using a "reader" which contacts the element via electrical probes to detect the change in resistance that is then equated to dose. contactless resistance measurement via rf probing is also highly possible.
