摘要

We simultaneously achieved low-voltage operation (-5 V) and large drain current (I-D) modulation in a dual-gate organic pressure sensor in which a piezoelectric layer was stacked on a low-voltage organic field-effect transistor (OFET). During testing, ID changed from 3.9 x 10(-9) to 2.5 x 10(-11)A when a 300 kPa pressure load was applied, and ID clearly responded to the pressure load and release. An endurance cycle test of the device was performed using a pressure load of 100 kPa, and the ID modulation was consistently reproduced throughout the test.
