Automatic test-bed for a multifunctional electrical stimulation system

Medical products of a manufacturer need to be conform with a lot of norms and policies in order to be allowed at the market. Therefore, every product has to be checked according to its functionality and safety before being sold. Because of the high numbers of produced devices and the partial lack of resources, it is recommended to service and test these products automatically.

The goal of this thesis is the development of an automatic testing system for a multifunctional electrical stimulator, which checks all included individual components against the defined specifications and thus allows an objective assessment of the functionality of the entire system. After the development and determination of appropriate test steps and test procedures for the present components, such as functional electrical stimulation (FES), transcranial electrical stimulation (tDCs), tactile stimulation and auditory stimulation, as well as a wireless EEG, component tests have to be implemented in a test setup by using the existing APIs. The results of the entire stimulation system as well as the individual single tests shall be documented in a final concluding test report. For this purpose, an own hardware and software, programmed in Python, are developed, which allow the measurement of the most important parameters and evaluate them automatically.
