Pressure sensors that combine piezoelectric materials with organic field-effect transistors (OFETs) are considered promising for fabricating highly sensitive sensors on flexible, curved substrates by utilizing printing techniques such as the extended meniscus-guided coating technique and the SuPR-NaP technique. In this study, aiming for practical applications, we focused on the low-pressure regime and investigated the behavior of the pressure sensor under various conditions by changing how to apply force to the piezoelectric material and altering the sample shape. The results of performance comparisons under each condition are reported.
