Abstract
The pressure-sensitive paint (PSP) technique has the potential as a diagnostic tool for measurement in the high Knudsen number regime because it works as a so-called "molecular sensor". However, application of the PSP technique to micro-systems is difficult because the conventional PSP is too thick owing to the use of polymer binder. We constructed pressure sensitive molecular film (PSMF), using Platinum(II) MesoporphyrinlX (PtMP), and have examined our PSMF to evaluate the possibility of application to the measurement of micro-flow. It is found that the pressure sensitivity of PtMP based PSMF is equal to the that of polymer PSP.
