Light-insensitive organic solar-powered amplifiers.

ABSTRACT: Wearable bio-sensors using organic electrochemical transistors (OECTs) powered by flexible organic solar cells (OSCs) show promise for electrophysiological monitoring. However, single OECT bio-sensors face unstable outputs due to the limitations of OSCs under low-light conditions and poor energy autonomy. Here, we show a low-power self-powered physiological sensor employing a dual-OECTs configuration, connected in series and powered by the optimized OSCs, which shows more stable signal output and faster response compared to single OECT bio-sensors. Our devices employ the efficient and more stable OSCs to power amplifier by suppressing charge recombination and improving flexibility, thereby facilitating long-term, on-demand use. This integrated device can be attached to human-skin to stably
