Resumo
The present work reports on the development of scientific instrumentation in scanning probe microscopy (SPM), a field of wide application and versatility that allows exploring surface properties at the atomic and molecular levels. Usually, SPM systems deliver information to the user with images that represent the surface properties. Here we implemented a realtime data sonification system that enables visually impaired people to perform SPM experiments and provides other information that is not nicely captured by the human eye. Based on a Raspberry Pi 3B + board and Python algorithms, our system generates parameters based on an SPM scan for sonification that is tested here using the MIDI (Musical Instrument Digital Interface).
