Smallest surface sensors using MEMS technology

28.04.2011

How rough, how smooth, how hard, how deformable? Exact surface metrology is of great significance in many fields of research and production. It is, above all, in microsys-tems technology and in nanotechnology that geometric dimensions and surface proper-ties have to be measured with high precision. Scientists of the Physikalisch-Technische Bundesanstalt (PTB) have developed an entire portfolio of MEMS-based surface meas-uring devices, with which it is possible to measure the smallest path length changes and forces in a simple way. Today, MEMSs (Micro Electro Mechanical Systems) are em-ployed a millionfold, for example in automotive engineering. These MEMSs will also be used now for the first time for ultraprecision sensor systems. The MEMS-based surface measuring devices can be viewed from 7 to 9 June 2011 at the Nuremberg trade fair SENSOR + TEST 2011 in Hall 12, Stand 376.
