Fraunhofer's self-monitoring polymer-metal composite
When engineers want to know how much stress mechanical components such as wind turbine blades or machine parts are subjected to, they usually do so via a series of sensors. These sensors are typically either built into components, or are glued onto them. A new polymer-metal composite material developed at Germany’s Fraunhofer Institute for Manufacturing Technology and Applied Material Research (IFAM), however, may be about to change that – components made from the material are reportedly able to act as their own sensors.
