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.
