The pressure-sensitive paint (PSP) technique has potential as a diagnostic tool for pressure measurement of micro gas-flows because it is based on interaction of molecules with photons. However, the application of the PSP to micro-flows is very difficult, because the conventional PSP is too thick owing to polymer binder. In our previous work, we adopted Langmuir-Blodgett technique to fabricate a pressure sensitive molecular film (PSMF). In this study, we have constructed PSMF composed of Pt(II) Mesoporphyrin IX (PtMP) to be applied to pressure measurement near atmospheric pressure condition. The pressure sensitivity of PSMF-PtMP was tested, and it was clarified that the PSMF-PtMP has equivalent pressure sensitivity of polymer PSPs (e.g. PtOEP/GP-197). Moreover, we have applied PSMF to pressure measurement of a gas flow through the 170μm width micro-channel, and the pressure distribution on the surface along the channel was successfully obtained.
