Organic field-effect transistor (OFET) platforms are promising candidates for sensors due to low cost, biocompatibility, flexibility, and especially high sensitivity. In OFET-based sensors, charge carrier density can be changed by binding events with analytes, which can be amplified by modulating the gate voltage. In recent years, various health care devices have been developed with the increasing interest in human well-being. In particular, sweat sensors have been extensively investigated because it can detect the components of sweat related to health information as attached to the human body. We chose one target component, which can increase the risk of stress-related health conditions in sweat. For the active layer, a dibenzothiopheno[6,5‑b:6′,5′‑f]thieno[3,2‑b]thiophene (DBTTT) derivate was used due to its high mobility and superior water stability. Our approach offers a viable way for the fabrication of high-performance OFET-based sensors compared to classical sensor devices. |
