Long-term stable micro-macro coupling to build ultra-flat silicon strain sensors for macroscopic test specimens
German title: | Langzeitstabile Mikro-Makro-Kopplung zum Aufbau ultraflacher Siliziumdehnungssensoren für makroskopische Prüfkörper | |
Acronym: | Mikado | |
Duration: | 1st April 2019 - 30th September 2021 | |
Description: | A method for the assembly of novel force sensors with integrated silicon strain gages is required which meets the following requirements: Wire bonding of the Si strain gages before they are mounted on the test specimen. No wire bonding on the test specimen Long-term stable joining of the Si strain gages, preferably glass frit Low temperature load of the test specimen, partial heating is tolerable Universally applicable on test specimens of different geometry Preferably, a prefabricated sensor element, with Si strain gauge, printed circuit board, signal processing should be joined to the test specimen. As a typical value should be aimed for: Long-term stability in the nominal temperature range (-40°C to +80°C, max. 80%rh): 1 %measuring span/yr. By using the Si strain gages for force sensors and different test specimens under the boundary conditions set above, advantages and improvements are to be expected: Smaller and stiffer spring body to set up as a force sensor. Higher measuring span Easier realization of multi-component force sensors due to the integrated full bridge | |
