The Swiss Federal Laboratories for Materials Science and Technology (Empa,[1] German acronym for Eidgenössische Materialprüfungs- und Forschungsanstalt) is an interdisciplinary Swiss research and service institution for applied materials sciences and technology. As part of the Swiss Federal Institutes of Technology Domain, it is an institution of the Swiss federation. For the longest time since its foundation in 1880, it concentrated on classical materials testing. Since the late 1980s it has developed into a modern research and development institute.
