Event description
Organic semiconductors offer unique advantages - mechanical flexibility, biocompatibility, low-cost processing, and tunable optoelectronic properties - making them ideal for next-generation photodetectors and bioelectronic devices. Recent advances have enabled organic photodetectors (OPDs) with performance
metrics approaching those of established inorganic technologies.
Through molecular design, exciton dynamics, and refined device architectures, OPDs now demonstrate low dark currents, high specific detectivity, fast temporal response, and tunable spectral sensitivity from the visible to the near-infrared. Techniques such as photomultiplication provide high gain, while low-donorcontent architectures and trap management reduce noise and dark currents, facilitating filterless spectral selectivity. Semitransparent, flexible OPDs processed via physical vapor deposition expand possibilities for large-area sensors in NIR communication, imaging, and spectroscopic sensing.
Beyond classical optoelectronic applications, organic materials are advancing in bioelectronic as wearable and implantable systems. Their mechanical compliance and tunable conductivity facilitate seamless interfacing with biological tissues for real-time health monitoring, biosensing, and therapeutics. Advances
encompass organic thin-film transistors, sensors, and light-emitting components integrated into conformable wearables for pulse oximetry, biometric detection, and continuous physiological tracking.
