The Swiss Federal Laboratories for Materials Science and Technology or Empa (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 Institute of Technology (ETH) Domain ("ETH-Bereich") 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.
