We report on original industrialized functional testing methods for insulin micropumps.A specific Design-For-Test associated with the analysis of the integrated pressure sensor signal, during a specific actuation profile, allows a complete characterization of the pump functionality in few seconds.All critical failures due to fabrication and assembly create clear and specific deviations from nominal signal.The pressure sensor sensitivity coupled to the high compression ratio and the small dead volume of the micropump lead to a leak detection sensitivity of only few nl/h for water or insulin at 37°C.
