Triboelectric phenomenon, historically, is one of many problems which engineers wantedto be avoid. However nowadays this phenomenon seems to be useful source of electrical signalfor displacement measurement. In this work all sensing elements are made from pure PVDF byelectrospinning manufacturing method. Nano fibres, which are result of the process are placed toaluminium foil naturally without mechanical rectifying. Used material was tested only for triboelectriccharge generation, although piezoelectric phenomenon was expected. We were not able toquantify it by standard methods, probably due to chaotic structure and fabric behaviour of the finalproduct. Triboelectric phenomenon is possible to measure directly, and systems are more predictable.Finally, two modes were tested, and potential advantages and disadvantages were qualified.
