Flexible Electronics Fabrication and Control Responsiveness for Device Reliability in Wearable Healthcare Prototypes

Abstract

Wearable healthcare prototypes have emerged as a cornerstone of personalized medicine, enabling continuous, non-invasive physiological monitoring. However, ensuring mechanical and electrical reliability remains a critical bottleneck due to the mismatch between rigid electronic components and soft, dynamic human skin. This paper investigates the symbiotic relationship between advanced flexible electronics fabrication techniques and real-time control system responsiveness in guaranteeing device-level reliability. We present a comprehensive framework that integrates elastomer-based substrate engineering with a proactive closed-loop control system. Through systematic cyclic stress testing and signal-to-noise ratio characterization, we demonstrate how high fabrication precision reduces mechanical fatigue and contact impedance. Concurrently, we analyze how adaptive control loops compensate for physical degradation and motion-induced artifacts. Our findings reveal that combining micro-patterned serpentine interconnects with dynamic feedback control algorithms maintains signal integrity and reduces device latency, even under severe mechanical deformation. This dual-optimization strategy offers a clear pathway for developing robust, clinical-grade wearable diagnostics capable of long-term deployment in unpredictable daily environments.
