Challenges: Scalability, Reliability, and Integration with Electronics

Polymer-based flexible biosensors are at the forefront of next-generation wearable and implantable health monitoring devices, but their widespread adoption in 2025 and beyond is constrained by several persistent challenges—most notably scalability, reliability, and seamless integration with electronic systems.

Scalability remains a significant hurdle. While laboratory-scale fabrication of polymer-based biosensors using techniques such as inkjet printing, screen printing, and roll-to-roll processing has demonstrated promising results, translating these methods to high-throughput, cost-effective industrial production is complex. Issues such as uniformity of polymer films, reproducibility of sensor performance, and yield losses during mass production are critical. Leading materials suppliers and electronics manufacturers, such as DuPont and Kuraray, are investing in advanced polymer formulations and scalable processing technologies to address these bottlenecks. For example, DuPont has developed specialized conductive inks and flexible substrates tailored for roll-to-roll manufacturing, aiming to improve throughput and consistency for biosensor applications.

Reliability is another pressing concern, particularly for biosensors intended for long-term or continuous use. Polymers, while offering flexibility and biocompatibility, can be susceptible to degradation from moisture, temperature fluctuations, and mechanical stress. This can lead to drift in sensor readings or outright device failure. Companies like Kuraray and Arkema are developing advanced polymer blends and encapsulation materials to enhance environmental stability and mechanical robustness. Additionally, the integration of self-healing polymers and protective coatings is being explored to extend device lifetimes and maintain sensor accuracy over prolonged periods.

Integration with electronics is a third major challenge.
