摘要
Organic electrochemical transistors(OECTs)are promising technologies for biosensing and braininspired computing due to their low-power signal amplification and neuron-like behavior.However,their manufacturing remains complex,especially when fabricated into flexible forms.To address the growing demand for flexible OECTs in wearable bioelectronics,in this work,we propose:i)a rapid and low-cost fabrication approach using flexible PCB(fPCB)technology and customized inkjet printing;ii)a non-aqueous gel-gated approach to improve the electrochemical stability of flexible OECTs associated with fPCBs;and iii)the above two approaches help accomplish the following concept:lowcost,integrated,and in-sensing computing system can be more readily realized with flexible OECT devices.This platform has been validated for scalability,stability,and performance in real-world applications,paving the way for developing low-cost,flexible,multifunctional OECT systems.
