Tiivistelmä
Stretchable electronics being a fast growing and developing field both commercially and as a study field, the need to put effort on quality increases. Because stretchable electronics is also rather a new field, there are no tester, standard or practices ready but all must be designed and created. Because of this, the data handling has been done manually and the surplus of data is laborious to handle.
This thesis was written in a Finnish stretchable electronics company and is a part of the internal development of the company. The goal was to design a universal test electronics to act as an interface between a tester and a PC in an automated test system. The first phase in the project was to choose components and design the schematics of the test electronics. The second phase was to write embedded software for the test electronics in C-language. Lastly, the software was tested by performing measurements on three stretchable samples in a so-called Press & Bend test.
The developing of the automated test system will continue and the universal test electronics and the embedded software are an integral part of the system. This thesis has provided a good basis for the test system and offered insight on how the developing should be continued.
