Abstract
Lightweight, flexible, and conformal bioelectronics are essential for wearable technologies. This paper introduces 270 nm thin organic electronics amplifying circuits that are self-adhesive, skin conformal, and long-term air-stable. This report studies the effect of total device thickness, namely 3 μm and 270 nm devices, on the characterization of organic devices before and after buckling, the longevity of organic field-effect transistors (OFETs) over 5 years, and the lamination of OFETs on the human skin. A single-stage organic complementary inverter and a pseudo-complementary amplifier are fabricated to compare their electrical characteristics, with amplification gains of 10 and 64, respectively. Finally, the study demonstrates a five-stage organic complementary inverter can successfully amplify artificial electromyogram and electrocardiogram signals with gains of 1000 and 1088, respectively.
