Paradigm shift in wearable bioelectronics: Drift-free organic field-effect transistor biosensors enabled by diode-connected pairs

Abstract

Organic field-effect transistor (OFET)-based biosensors are promising for wearable technology due to their good flexibility and low-cost fabrication. However, their susceptibility to signal drift from mechanical stress and environmental factors like temperature has been a major limitation. In this Commentary, we highlight a novel strategy that fundamentally redesigns the OFET biosensing circuit to eliminate the drifts.
